[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-4 As shown, a height-adjustable electrically driven rail-mounted operating frame includes a vertical frame assembly, a cantilever frame assembly, and a traveling wheel assembly. The lower end of the vertical frame assembly is connected to the traveling wheel assembly, which is rolled on the rail to enable the operating frame to travel on the rail surface. One end of the vertical frame assembly is connected to the height-adjustable cantilever frame assembly for workers to stand and operate the equipment.

[0021] Specifically, the support frame assembly includes two disc buckle uprights 1 and two steel pipe uprights 2. The two disc buckle uprights 1 and the two steel pipe uprights 2 are arranged in a square shape and are connected by multiple first connecting steel pipes 3 at equal intervals. The two disc buckle uprights 1 are connected by multiple disc buckle crossbars 14 arranged at equal intervals.

[0022] Specifically, the walking wheel assembly includes four track-walking U-shaped wheels 4, with an upper insertion rod 5 connected to the upper end of each track-walking U-shaped wheel 4. Each upper insertion rod 5 is inserted into the lower end of the corresponding disc buckle upright 1 and steel pipe upright 2. It also includes a metal plate shelf 10, with four track-walking U-shaped wheels 4 connected to its four corners. The metal plate shelf 10 is equipped with a drive motor 11, the output end of which is connected to a differential 12, and the output end of the differential 12 is connected to one track-walking U-shaped wheel 4.

[0023] Specifically, it further includes a concrete counterweight 13 arranged on the iron plate shelf 10 away from one end of the cantilever assembly. The counterweight adopts a finished concrete block, and the weight of a single block is 25 kg. During platform operation, a standard configuration of 4 counterweights per person is adopted to prevent the frame from overturning. It also includes a battery 15 electrically connected to the drive motor 11. It also includes a remote control 16 connected to the drive motor 11 through a line communication. The battery serves as a power source, the DC motor outputs power, the differential controls the walking speed, and the motor driver and remote control combination controls the forward, backward and stop of the operation frame.

[0024] Specifically, the cantilever assembly includes two disc buckle cantilever tripods 6, which are respectively clamped on two disc buckle vertical rods 1. Each of the two disc buckle cantilever tripods 6 is connected with a vertical steel pipe 7, and the vertical steel pipe 7 and the disc buckle vertical rod 1 are connected through a plurality of disc buckle crossbars 8 arranged at equal distances.

[0025] Before use, the operator first adjusts the height according to the construction requirements using the disc buckle cantilever tripod 6 outside the disc buckle vertical rod 1, and realizes accurate positioning through the disc buckle pin and the lifting tripod to meet the height requirements of different track areas. After adjusting the height, the components are firmly connected using the steel pipe fastener to build a stable frame structure. Then, the motor drive system is started, and the track walking system drives the operation frame to move smoothly along the track to the designated operation area by operating the remote control. The operator can safely carry out operations on the cantilever operation platform, and the frame disc buckle crossbar also serves as a protective barrier to further ensure operation safety. After the operation at a single location is completed, the frame is moved to the next operation area.

[0026] In application scenarios, the operation frame has wide applicability. In subway side wall mechanical and electrical installation, decoration, equipment maintenance, leakage treatment and other operations, it can efficiently complete related operations with its height adjustment and cantilever operation functions. In the face of continuous operation tasks in long track sections, the electric drive walking system of the operation frame can quickly switch operation points to reduce the time and physical consumption of traditional manual carrying of the frame. When there are complex structures such as contact rails and sleepers in the track area, the track walking system is not hindered and can freely shuttle, effectively solving the problem that traditional elevated vehicles and simple operation frames cannot operate, greatly improving the efficiency and safety of high-altitude operations in track areas, and being suitable for urban rail transit engineering civil defect treatment, mechanical and electrical decoration, operation and maintenance, etc. in multiple stages.

[0028] The height-adjustable electric drive track surface walking operation frame connects the walking wheel assembly to the lower end of the stand assembly, the walking wheel assembly is rollingly connected to the rail to realize the walking of the operation frame on the track surface, one end of the stand assembly is connected to the cantilever frame assembly with adjustable height for the standing construction operation of the worker, a stable three-dimensional support structure is constructed, the high-falling safety hazard is greatly reduced, the integrated track surface walking system and motor driving system enable the operation frame to move smoothly along the track surface, completely get rid of the difficulties of the climbing vehicle being limited by the rail sleeper and the simple frame body relying on manual transportation, especially suitable for long-line continuous operation scenes, greatly reduces the consumption of manpower, and improves the construction efficiency.

[0029] In terms of functional adaptability and operation range, it has shown significant advantages. In view of the problems that the traditional track plate vehicle has no height adjustment function and cannot meet the lateral operation demand, and the simple frame body cannot be placed after the installation of the contact rail, the cantilever tripod outside the disc buckle vertical rod is used to realize flexible height adjustment, so as to adapt to the height difference requirements of various operations in different track areas to the greatest extent. The cantilever operation platform configured by the cantilever operation platform breaks through the limitation of the traditional equipment that can only be vertically operated, and provides stable operation space for lateral operation of mechanical and electrical equipment, decoration, leakage treatment and the like. The electric drive walking system is not affected by the sleeper and the contact rail, and can freely move after the track is laid, effectively solves the application bottleneck of the traditional mode in multiple working conditions, and realizes full-scene coverage of lateral operation at high places in the track area.
