The invention discloses a simple gantry crane, and relates to the technical field of building equipment. The simple gantry crane comprises a supporting frame, wherein a connecting block is arranged atthe lower end of the supporting frame, a bottom frame is arranged at the lower end of the connecting block, a hoisting device is arranged at the upper end of the supporting frame, the supporting frame comprises a frame body, a first rectangular groove and a second rectangular groove, the first rectangular groove is formed in the middle of the front surface of the frame body, the second rectangular groove is formed in the lower end of the front surface of the frame body, the lower ends of the left face and the right face of the frame body are each provided with two first circular grooves, theupper end of the rear surface of each first rectangular groove is provided with a third rectangular groove, the left-right position of the supporting frame is changed through sliding of pulleys in a fifth rectangular groove, compared with a traditional gantry crane, the hoisting range is enlarged by changing the front and rear position of a lifting hook through a motor, after the hoisting device ascends to the upper end of the supporting frame, a clamping block is extruded into the third rectangular groove, after a vertical rod ascends to the top end, the clamping block returns to the originalposition under the action of a spring, the hoisting device is fixed to the height, a pull ring can be pulled away through a climbing frame to enable the hoisting device to descend, and the hoisting device is convenient to mount and dismount.
本发明公开了一种简易龙门吊,涉及建筑设备技术领域。该一种简易龙门吊,包括支撑架,支撑架下端设置有连接块,连接块下端设置有底架,支撑架上端设置有起吊装置,支撑架包括架体、矩形凹槽一和矩形凹槽二,矩形凹槽一设置在架体的前表面的中间部分,矩形凹槽二设置在架体的前表面的下端,架体的左右两面的下端均设置有两个圆槽一,矩形凹槽一后表面的上端设置有矩形凹槽三,通过滑轮在矩形凹槽五内滑动来改变支撑架的左右位置,通过电机改变吊钩的前后位置,相比传统龙门吊增大了吊取范围,起吊装置上升至支撑架上端后,将卡块挤压至矩形凹槽三内,当竖杆上升至顶端后,卡块在弹簧作用下返回原位,使得起吊装置固定在该高度,通过攀爬架可拉去拉环使起吊装置下降,便于安装和拆卸起吊装置。
