Description
Technical Field
The utility model relates to maintenance equipment, in particular to a single-track maintenance device.
Background
The straddle type sightseeing monorail system is used for serving tourist attractions or connecting the attractions with other public transportation sites and provides a facility for tourists to connect in short distance and sightseeing. The vehicle adopts rubber wheels to straddle on a beam-rail integrated track beam. Besides the running wheels, the guide wheels and the stabilizing wheels are arranged on two sides of the bogie and clamped on two sides of the track beam, so that the vehicle can safely and stably run along the track.
Different from the traditional urban rail transit system, the track beam of the straddle-type sightseeing monorail system is generally laid in an overhead manner through steel upright posts, sliding contact wires, cables and other devices are arranged on webs on two sides of the track beam, the track beam is connected with upright post supports, and high-strength bolts are needed to be checked and maintained regularly, so that a simple, light and reliable working platform is needed to be carried on a working vehicle, the extending range of the platform covers the working area on the track beam, the engineering operation line of the straddle-type sightseeing monorail system in China is less, the body of the existing working platform is large, for example, the extending of the patent 20080066815. X adopts an inner cylinder and an outer cylinder to conduct guiding, when the extending stroke is enlarged, the expansion is in a 'lap' sinking state due to the dead weight and the bearing weight of the platform, the inner cylinder and the outer cylinder are in an extrusion state, the expansion is easy to be blocked, and cannot be horizontally retracted after the extension, if the platform cannot be fully retracted in time, the vehicle cannot return to a base, so that the line is occupied, and normal line operation is affected.
Disclosure of Invention
In order to solve the problem that an operation platform is easy to be unfolded and is easy to be blocked and unstable in operation in the prior art, the utility model adopts the following technical scheme:
the utility model provides a single track is striden a seat type maintenance device, is including striding the operation dolly of striding on the monorail operation dolly frame below suspension work platform, work platform include extension frame and crane, the extension frame on be provided with and supply the extension frame to hang the gyro wheel that can walk along single track width direction on the operation dolly frame extension frame and operation dolly between be provided with the extension hydro-cylinder that drives the extension frame and remove, the crane activity set up on the extension frame crane and extension frame between be provided with the lift cylinder that can drive the crane and rise or descend.
Further, the bottom of the lifting frame is hinged with an expansion frame which can be overturned to increase the base space of the expansion frame.
Furthermore, the operation platform is symmetrically provided with a pair of hanging devices below the frame of the running trolley.
Because the operation platform is hung on the frame of the operation trolley through the rollers and is driven to extend through the hydraulic cylinder, the frame can provide stable support for the operation platform and can provide smooth movement, and the phenomenon that clamping stagnation cannot be unfolded or retracted is avoided.

Detailed Description
In order to better understand the technical scheme of the present utility model, the following description is further made with reference to the accompanying drawings and specific embodiments.
The single track straddle type maintenance device shown in fig. 1 comprises a running trolley 1, the running trolley 1 and a straddle type single track vehicle are like in structure, the running trolley 1 runs on the single track through wheel groups, a working platform 2 is hung below a frame 1-1 of the running trolley 1 as shown in fig. 2, the working platform 2 comprises an extension frame 2-1 and a lifting frame 2-2 as shown in fig. 2 and 3, the working platform 2 can be hung below the frame of the running trolley 1, rollers 2-3 are arranged at the top of the extension frame 2-1 as shown in fig. 4, the extension frame 2-1 is hung on the frame of the running trolley 1 through the rollers 2-3, if no corresponding hanging part exists on the frame 1-1 of the running trolley, a corresponding cross beam 1-2 needs to be arranged on the frame 1-1 to provide hanging points for the rollers 2-3 and serve as guide rails, the rollers rolling surface is of a groove type, the rollers 2-3 can roll along the width direction on the cross beam 1-2 and do not move along the length direction of the single track, and therefore the single track 2 is arranged along the width direction of the single track 1 or the width direction of the single track 2 needs to be arranged on the frame 1-2. In order to enable a worker to have enough operation space during overhauling and maintenance work, and the overhauling device is as compact as possible to avoid interference operation when moving on the monorail, an extension cylinder 3 is arranged between the extension frame 2-1 and the operation trolley 1 as shown in fig. 2, one end of the extension cylinder 3 is connected with the extension frame 2-1, the other end of the extension cylinder is connected with the frame 1-1, the operation platform 2 can be driven to be far away from the monorail or approach to the monorail through the extension cylinder 3, enough space can be formed between the operation platform 2 and the monorail when the operation platform 2 moves away from the monorail, and the whole width of the overhauling device can be reduced when the operation platform 2 approaches to the monorail, so that the structure is compact to avoid influencing the operation of the overhauling device on the rail.
The working platform 2 shown in fig. 3 further comprises a lifting frame 2-2, wherein the lifting frame 2-2 is slidably arranged on the extending frame 2-1, the lifting frame 2-2 is synchronously unfolded or retracted along with the extending frame 2-1, a guide rail 2-5 for the lifting frame 2-2 to move is arranged on the extending frame 2-1 for enabling the lifting frame 2-2 to move smoothly and stabilizing the moving direction, a guide wheel 2-8 arranged in the guide rail 2-5 is arranged on the lifting frame 2-2, a lifting cylinder 4 for driving the lifting frame 2-2 to lift is further arranged between the extending frame 2-1 and the lifting frame 2-2, two ends of the lifting cylinder 4 are respectively connected with the extending frame 2-1 and the lifting frame 2-2, the lifting cylinder 4 can drive the lifting frame 2-2 to fall down so as to further increase the height direction space, and when the maintenance device runs normally on a monorail, the lifting frame 2-2 is required to be retracted through the lifting cylinder 4, the volume of the maintenance device is reduced, and the maintenance device is prevented from exceeding the limit of the vehicle, and the normal running of the running trolley 1 is affected.
In order to further increase the activity space of the working platform 2, as shown in fig. 5, an expansion frame 2-4 is hinged on the lifting frame 2-2, when the maintenance work is not performed, the expansion frame 2-4 is retracted inside the lifting frame 2-2, and when the maintenance work is performed by a worker, the bottom area of the lifting frame 2-2 can be further increased by turning over the expansion frame 2-4 for the operation of the worker. In order to enable the extension frame 2-4 to be positioned at a fixed position, a baffle plate 2-6 and a stop block 2-7 are respectively arranged on the extension frame 2-4 and the lifting frame 2-2 to realize limit and prevent the extension frame 2-4 from overturned excessively.
Because both sides of the track are possible to overhaul and maintain, two operation platforms 2 can be symmetrically arranged at both sides of the running trolley 1, so that both sides of the track can be overhauled and maintained conveniently.
