Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary equipment for hydraulic supports, and more specifically, to an anti - toppling device for advanced supports. Background Art
[0002] Due to the narrow and high body of the advanced hydraulic support, although there is the extrusion of the upper and lower roof plates and the interaction of the adjustment jacks between the left and right roof beams during the underground use process, it can achieve the anti - toppling effect during the support and the lowering and moving processes of the support. However, during the ground assembly and commissioning process, due to the lack of the extrusion conditions of the underground roof and floor, the narrow and high support loses its lateral stability and has a potential safety hazard of lateral tipping.
[0003] Therefore, it is necessary to improve the existing technology. Summary of the Utility Model
[0004] In order to overcome the deficiencies in the prior art, an anti - toppling device for advanced supports is provided, which can prevent the lateral tipping of the hydraulic support during the ground assembly and commissioning process.
[0005] In order to solve the above - mentioned technical problems, the technical solution adopted by the present invention is as follows:
[0006] An anti - toppling device for advanced supports includes a stable seat. Grooves for placing the support base are provided on both sides of the stable seat. A horizontally placed locking jack is provided on one side of each groove, and a positioning block for cooperating with the locking jack is fixedly provided on the other side of the groove;
[0007] The locking jack is connected with a one - way lock through a hydraulic pipeline, and the one - way lock is connected with a pump station through a hydraulic pipeline.
[0008] Preferably, a jack placement cavity is provided in the middle of the stable seat. Both locking jacks are arranged in the jack placement cavity and the piston rods point to the corresponding groove directions. The rear end of the cylinder body of the locking jack is connected with the jack placement cavity through a pin shaft;
[0009] A semi - circular groove is provided at the end of the jack placement cavity. The front end of the cylinder body of the locking jack is arranged in the semi - circular groove and is fastened by a half - tile. The half - tile and the semi - circular groove are connected through a fastener.
[0010] Preferably, a cover plate is provided at the upper end of the jack placement cavity, and the cover plate is connected with the jack placement cavity through bolts.
[0011] Preferably, the two grooves are symmetrically arranged with respect to the stable seat.
[0012] Preferably, two stable seats form a group, and both sides of the support base are respectively arranged in the grooves of the two stable seats.
[0013] Preferably, the width of the groove is 1000 mm ± 100 mm, and the depth is 400 mm ± 50 mm.
[0014] Working principle:
[0015] When assembling the advanced hydraulic support, the stabilizing seats are used in pairs of two, and one is placed under the appropriate positions at the front and rear of the advanced hydraulic support. First, place the base of the advanced hydraulic support in the grooves of the two anti-toppling devices, and then press and fix the base of the advanced hydraulic support by actuating the piston rod of the locking jack. After the base of the advanced hydraulic support is firmly fixed, the lower cavity of the locking jack is locked by the one-way lock. In this way, the base of the advanced hydraulic support is not only firmly fixed, but also forms an integral body.
[0016] The beneficial effects of the present invention compared with the prior art are as follows:
[0017] By connecting the base of the advanced hydraulic support with the stabilizing seat through the stabilizing seat, the locking jack, and the one-way lock, the stability of the advanced hydraulic support is greatly enhanced, and the advanced hydraulic support can be safely assembled from bottom to top. The anti-toppling device plays a role in preventing the possible lateral toppling of the advanced hydraulic support, ensuring personal safety, and realizing safe and efficient production.
