Description

Technical Field

[0001] The invention relates to the technical field of lifting platforms, and specifically to a safe and stable crawler-type insulating lifting platform. Background Art

[0002] Vertical lifting platforms are commonly used equipment in engineering operations. They are generally single-mast, double-mast, scissor-type and other structures. The function of vertical lifting platforms is to carry workers to the designated position and stay at the corresponding height for a long time, so that workers can perform installation, maintenance and other related work.

[0003] When the existing lifting platform is in use, as the lifting platform lifts the workers, it is simply transporting the workers. However, when moving, the center of gravity of the lifting platform as a whole will continue to rise and move away from the ground, and then the workers are prone to shaking when performing high-altitude operations on its surface. This is very inconvenient for some power maintenance that requires high stability and is prone to the risk of falling. Therefore, a safe and stable crawler-type insulated lifting platform is particularly important. Summary of the invention

[0004] The purpose of the present invention is to provide a safe and stable crawler-type insulated lifting platform to solve the problem that the existing lifting platform proposed in the above-mentioned background technology is that when the lifting platform is in use, it is only for transporting the staff. However, when moving, the center of gravity of the lifting platform as a whole will continue to rise and move away from the ground, and then the staff will easily shake when performing high-altitude operations on its surface, which is very inconvenient for some high-stability power maintenance and is prone to the risk of falling.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a safe and stable crawler-type insulated lifting platform, comprising a connecting seat, a crawler mechanism is provided on the lower surface of the connecting seat, a plurality of support rods are provided on the upper surface of the connecting seat, the other end of the support rod is connected to a lifting platform, a hydraulic cylinder is provided between the support rods, one end of the lifting platform is rotatably connected to a baffle, the inner surface of the lifting platform is symmetrically slidably connected to a limiting block, a limiting plate is slidably connected between the two limiting blocks, and handles are symmetrically provided on the surface of the limiting plate.

[0006] Preferably, a first spring is provided between the two limit blocks, the other ends of the two first springs are connected to a connecting sleeve, the inner surface of the connecting sleeve is slidably connected to a connecting rod, the other ends of the two connecting rods are fixedly connected to the limit plate, and a buffer cotton layer is provided on the surface of the limit sleeve.

[0007] Preferably, the inner side wall of the lifting platform is symmetrically provided with a slide groove and a steel mesh, the limit block is slidably connected to the slide groove, and buffer springs are symmetrically provided at both ends of the slide groove.

[0008] Preferably, a support frame is provided on the upper surface of the connecting seat, and the support frame is located outside the support rod and has a horizontal position higher than the support rod.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The staff enters the surface of the lifting platform from the baffle and then drills into the center area of ​​the limit plate. The height of the limit plate is just at the waistline of the staff. At the same time, the limit plate can be moved back and forth and left and right on the surface of the lifting platform under the action of the staff, which is convenient for the staff's construction. In the process of lifting and lowering the support rod and the hydraulic cylinder, the overall connection between the staff and the lifting platform is strengthened, which reduces the situation of the staff's unstable center of gravity as the lifting platform rises, effectively protects the staff, and reduces the risk of staff falling.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The specific connection relationship between the limit block 7 and the limit plate 8 is that a first spring 10 is provided between the two limit blocks 7, the other ends of the two first springs 10 are connected with a connecting sleeve 11, the inner surface of the connecting sleeve 11 is slidably connected with a connecting rod 12, the other ends of the two connecting rods 12 are fixedly connected to the limit plate 7, and a buffer cotton layer 13 is provided on the surface of the connecting sleeve 11, wherein the limit plate 8 can move back and forth between the two connecting sleeves 11 through the connecting rod 12 to adjust the specific position of the staff, and under the action of the buffer cotton layer 13 and the first spring 10, the impact effect generated during movement is reduced to effectively protect the staff.

[0019] The specific structure inside the lifting platform 4 is as follows: the inner side wall of the lifting platform 4 is symmetrically provided with a slide groove 14 and a steel mesh 15; the limit block 7 is slidably connected to the slide groove 14; buffer springs 16 are symmetrically provided at both ends of the slide groove 14; when the limit plate 8 moves in the front-rear direction, the limit block 7 moves on the inner surface of the slide groove 14; the specific boundary of the movement can be determined by setting the buffer spring 16; at the same time, the limit block 7 can be effectively buffered when moving to reduce the impact effect; at the same time, the steel mesh 15 can effectively block foreign objects while ensuring the circulation of air, thereby reducing the effect of wind on the lifting platform.

[0020] The function of the support frame 17 is that a support frame 17 is provided on the upper surface of the connecting seat 1, and the support frame 17 is located outside the support rod 3 and is horizontally higher than the support rod 3. Through the function of the support frame 17, when the hydraulic cylinder 5 fails, the support rod 3 cannot be effectively supported, which causes the lifting platform 4 to fall, squeeze the support rod 3, and cause the lifting platform 4 to be unstable. The setting of the support frame 17 can protect the emergency landing of the lifting platform 4, provide effective support, and protect the staff.

[0021] Working principle: When in use, first control the crawler mechanism 2 to move to the area to be processed through the external controller, then the staff opens the baffle 6 to enter the surface of the lifting platform 4, then passes through the limit plate 8, and then closes the baffle 6, and drives the hydraulic cylinder 5 to release through the external controller, driving the support rod 3 to rotate, and lifting the lifting platform 4. After lifting it to the specified height, the staff can move on the surface of the lifting platform 4 under the protection of the limit plate 8 to carry out construction.
