Description

Technical Field

[0001] This utility model relates to the field of aerial work platform structure technology, and in particular to an aerial work platform structure for a mining aerial work platform. Background Technology

[0002] Aerial work platform vehicles, also known as lifting platform trucks or aerial work vehicles, are mechanical equipment used for indoor and outdoor high-altitude operations. Their main function is to lift workers and materials to a designated height via a lifting device for maintenance, installation, inspection, cleaning, and other operations. The main components include a frame, lifting device, work basket, and electrical control system.

[0003] The aerial work platform's climbing structure mainly consists of a base, a scissor lift mechanism, a work platform, a hydraulic system, and outriggers. In existing technology, the outriggers of the aerial work platform's climbing structure are responsible for stabilizing the base, while the scissor lift mechanism and hydraulic system are responsible for raising the work platform. This type of aerial work platform's climbing structure has several problems when in use: first, the surface under the work basket lacks a cushioning structure, making workers prone to injury when the work basket descends rapidly due to unexpected circumstances; second, the lower ends of the outriggers do not fit snugly against the ground. Utility Model Content

[0004] The main purpose of this utility model is to provide a mining aerial work platform structure that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A mining aerial work platform structure includes a base plate. Platform supports are fixedly installed on the lower surface of the base plate near the four corners. A scissor lift structure is fixedly installed at the center of the upper surface of the base plate. A work guardrail frame is fixedly installed on the upper surface of the scissor lift structure. Buffer bars are fixedly installed on the upper surface of the base plate near the four corners, and the upper ends of the buffer bars are fixedly connected to the four corners of the work guardrail frame.

[0007] Preferably, the platform support includes a limiting hollow pile, a supporting crossbar, an electro-hydraulic outrigger, a ball-head pile, an outrigger disc, and a rubber ring.

[0008] Preferably, the limiting hollow pile is fixedly installed on the lower surface of the base plate near the four corners, the supporting crossbar is sleeved on the outside of the limiting hollow pile, and the electro-hydraulic outrigger is fixedly installed inside the cylinder at the front end of the supporting crossbar.

[0009] Preferably, the ball head pile is fixedly installed at the lower end of the electric hydraulic outrigger, the outrigger disc is sleeved on the lower end of the ball head pile, and the rubber ring is fixedly installed on the lower surface of the outrigger disc.

[0010] Preferably, the buffer rod includes a first tube, a cross-shaped through-hole rubber sleeve, a second tube, a third tube, a fourth tube, a first sealing ring, a second sealing ring, and a third sealing ring.

[0011] Preferably, the first tube is fixedly installed on the upper surface of the base plate near the four corners, and the cross-shaped through-hole rubber sleeve is fixedly installed in the circular through-hole on the lower surface of the first tube.

[0012] Preferably, the second pipe is located inside the first pipe, the third pipe is located inside the second pipe, and the fourth pipe is located inside the third pipe. The first sealing ring is fixedly installed on the outside of the second pipe at the lower end, the second sealing ring is fixedly installed on the outside of the third pipe at the lower end, and the third sealing ring is fixedly installed on the outside of the fourth pipe at the lower end. Annular grooves are formed on the outer sides of the first, second, and third sealing rings.

[0013] This utility model features a buffer bar that increases the stability of the scissor lift structure. When the working guardrail frame descends unexpectedly, the buffer bar acts as a buffer, greatly slowing down the descent speed of the working guardrail frame and ensuring the safety of the mining aerial work vehicle during aerial operations.

[0014] The platform supports can stably support the four corners of the base plate, allowing it to fit more closely to the ground, providing anti-slip properties and increasing stability during high-altitude operations. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-5 As shown, a mining aerial work platform structure includes a base plate 1. Platform supports 2 are fixedly installed on the lower surface of the base plate 1 near the four corners. A scissor lift structure 3 is fixedly installed at the center of the upper surface of the base plate 1. A working guardrail frame 4 is fixedly installed on the upper surface of the scissor lift structure 3. Buffer bars 5 are fixedly installed on the upper surface of the base plate 1 near the four corners. The upper ends of the buffer bars 5 are fixedly connected to the four corners of the working guardrail frame 4. The base plate 1 is installed on the mining aerial work platform.

[0023] In this embodiment, the platform support 2 includes a limiting hollow pile 201, a supporting crossbar 202, an electric hydraulic outrigger 203, a ball-head pile 204, an outrigger disc 205, and a rubber ring 206.

[0024] In this embodiment, the limiting hollow pile 201 is fixedly installed on the lower surface of the base plate 1 near the four corners, the supporting crossbar 202 is sleeved on the outside of the limiting hollow pile 201, and the electric hydraulic outrigger 203 is fixedly installed in the cylinder at the front end of the supporting crossbar 202.

[0025] In this embodiment, the ball-head pile 204 is fixedly installed at the lower end of the electric hydraulic outrigger 203, the outrigger disc 205 is sleeved on the lower end of the ball-head pile 204, and the rubber ring 206 is fixedly installed on the lower surface of the outrigger disc 205. During the climbing operation, when supporting the four corners of the base plate 1, the support crossbar 202 can rotate outside the limiting hollow pile 201 to adjust the support crossbar 202 to a suitable angle. The electric hydraulic outrigger 203 supports the ball-head pile 204 downwards, and the outrigger disc 205 can slide outside the ball-head pile 204, making the outrigger disc 205 more in contact with the ground. The rubber ring 206 plays an anti-slip role. The platform bracket 2 can stably support the four corners of the base plate 1, can be more in contact with the ground, has an anti-slip role, and increases the stability during the climbing operation.

[0026] In this embodiment, the buffer rod 5 includes a first tube 501, a cross-shaped through-hole rubber sleeve 502, a second tube 503, a third tube 504, a fourth tube 505, a first sealing ring 506, a second sealing ring 507, and a third sealing ring 508.

[0027] In this embodiment, tube 501 is fixedly installed on the upper surface of the base plate 1 near the four corners, and cross-shaped through-hole rubber sleeve 502 is fixedly installed in the circular through-hole on the lower surface of tube 501.

[0028] In this embodiment, pipe 2 503 is located inside pipe 1 501, pipe 3 504 is located inside pipe 2 503, and pipe 4 505 is located inside pipe 3 504. Sealing ring 1 506 is fixedly installed on the lower outer side of pipe 2 503, sealing ring 2 507 is fixedly installed on the lower outer side of pipe 3 504, and sealing ring 3 508 is fixedly installed on the lower outer side of pipe 4 505. Annular grooves are formed on the outer sides of sealing rings 1 506, 2 507, and 3 508. After the working guardrail frame 4 rises, pipe 4 505 is pulled out of pipe 3 504, pipe 3 504 is pulled out of pipe 2 503, and pipe 2 503 is pulled out of pipe 1 501. Sealing rings 1 506, 2 507, and 3 508 provide a seal. The annular grooves on the outer sides of the No. 1 sealing ring 506, No. 2 sealing ring 507, and No. 3 sealing ring 508 improve the sealing effect. Air is continuously introduced into the interior of the No. 1 pipe 501 through the through hole of the cross-hole rubber sleeve 502. When the working guardrail frame 4 descends due to accidents such as damage to the hydraulic rod inside the scissor lift structure 3, the No. 4 pipe 505, No. 3 pipe 504, and No. 2 pipe 503 are slowly reinserted into the interior of the No. 1 pipe 501. The air is discharged through the interior of the cross-hole rubber sleeve 502. The cross-hole rubber sleeve 502 increases the difficulty of air discharge, so that the working guardrail frame 4 can only descend slowly. The buffer rod 5 increases the stability of the scissor lift structure 3. When the working guardrail frame 4 descends in an accident, it plays a buffering role, greatly slowing down the descent speed of the working guardrail frame 4 and ensuring the safety of the mining aerial work vehicle during aerial operations.
