[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0028] See also Figures 1-4 , which shows a structural schematic diagram of a tooling vehicle provided by the present invention that is suitable for use in confined spaces in long-distance pipeline corridors.

[0029] According to the drawing, the tool car suitable for long-distance pipe gallery restricted space provided by the utility model comprises seven components, i.e., a track 100, a mobile chassis 200, a construction platform 300, a ladder 400, two groups of telescopic cross arm assemblies 500, a plurality of springboards 600 and a control box 700.

[0030] The mobile chassis 200 is movably arranged on the track 100, the construction platform 300 is connected above the mobile chassis 200 through a plurality of connecting columns 310, and the length and width of the construction platform 300 are arranged along the length direction and the width direction of the track 100 respectively.

[0031] The ladder 400 is arranged between the construction platform 300 and the mobile chassis 200, and can be used for workers to climb from the mobile chassis 200 to the construction platform 300 along the ladder 400.

[0032] The two groups of telescopic cross arm assemblies 500 are arranged on the two sides of the construction platform 300 in the width direction and are telescopic.

[0033] In the folded state, the two groups of telescopic cross arm assemblies 500 are retracted into the construction platform 300 as a whole, so that the mobile chassis 200 can be moved.

[0034] In the unfolded state, the two groups of telescopic cross arm assemblies 500 are respectively extended outward along the two sides of the construction platform 300 in the width direction, and the plurality of springboards 600 are arranged on the telescopic cross arm assemblies 500 to form a temporary construction expansion platform.

[0035] The control box 700 is arranged on the mobile chassis 200 and connected with the mobile chassis 200 and the telescopic cross arm assemblies 500, and is used for controlling the movement of the mobile chassis 200 and the telescoping of the telescopic cross arm assemblies 500.

[0036] Compared with the prior art, the tool car provided by the scheme can form a folded state and an unfolded state through telescoping, the overall structure occupies a small space in the folded state, and the tool car is convenient to move, and after being moved to a work site, the tool car is switched to the unfolded state to form a temporary construction expansion platform, so that the work range is improved, and the tool car is suitable for restricted spaces such as pipe galleries.

[0037] Specifically, the track 100 is a conventional double-track track, which is not described here.

[0038] The mobile chassis 200 comprises a chassis body 210, a plurality of drive wheels 220 arranged at the bottom of the chassis body 210, the drive wheels 220 being movably arranged on the track 100, the control box 700 being arranged at the top of the chassis body 210, the plurality of drive wheels 220 being connected with the control box 700 respectively, and the drive wheels 220 being controlled by the control box 700.

[0039] In order to further improve the reliability of the movement of the mobile chassis 200, a caliper 230 is provided on the driving wheel 220, and the caliper 230 is connected to the control box 700. The control box 700 can control the caliper 230 to limit the rotation of the driving wheel 220, so that the driving wheel 220 is stationary on the track 100 and cannot move, thereby preventing the tooling vehicle from being displaced during use and preventing the mobile operating platform from overturning.

[0040] The construction platform 300 is a rectangular standing platform for workers to stand on. The bottom of the construction platform 300 is connected to the control box 700 through a number of connecting columns 310. This solution does not limit the connection method between the construction platform and the control box 700, which can be determined according to actual needs. For example, welding can be used for fixed connection, or threaded connection can be used for detachable connection.

[0041] The construction platform 300 is provided with through holes on both sides along its width direction, which can accommodate the retractable cross arm assembly 500 and are provided with a plurality of slide grooves;

[0042] In conjunction with this, two sets of retractable cross-arm assemblies 500 are symmetrically arranged in the through holes of the construction platform 300. When the retractable cross-arm assemblies 500 are folded, the two sets of retractable cross-arm assemblies 500 are placed in the through holes as a whole. When unfolded, the two sets of retractable cross-arm assemblies 500 extend outward toward both sides of the width direction of the construction platform 300.

[0043] The retractable crossbar assembly 500 includes several cross bars 510 and a retractable mechanism. Several cross bars 510 correspond to several slide grooves. A slider is provided at the bottom of the cross bar 510. The cross bar 510 is movably embedded in the slide groove through the slider. Several cross bars 510 are connected in series through connecting parts. The retractable structure is arranged in the through hole of the construction platform 300 and is connected to the connecting parts. The retractable mechanism is connected to the control box 700, and the start and stop of the retractable mechanism can be controlled by the control box 700.

[0044] This solution does not limit the specific structure of the telescopic mechanism, which can be determined according to actual needs. For example, a telescopic motor can be used.

[0045] In this way, in actual application, when arriving at the work site, the control box 700 controls the telescopic mechanism to extend outward, so that the several cross bars 510 move outward and unfold. At this time, several springboards 600 are laid on the several cross bars 510 to block the gaps between the several cross bars 510, thereby forming a temporary construction expansion platform for standing.

[0046] Furthermore, a plurality of stop posts 610 are sequentially provided on both sides of the springboard 600 in the longitudinal direction. The springboard 600 is arranged on the plurality of cross bars 510. The stop posts 610 on both sides are respectively located outside the two outer cross bars 510 among the plurality of cross bars 510. The stop posts 610 on both sides of the springboard 600 cooperate with the cross bars 510 to limit the movement of the springboard 600 in the longitudinal direction of the track 100.

[0047] Furthermore, in order to further improve safety during work and further limit the position of the crossbar 510, the work vehicle provided in this solution for the confined space of a long-distance pipeline corridor also includes a detachable protective fence assembly 800. The detachable protective fence assembly 800 is located outside the construction platform 300 and the temporary construction expansion platform to prevent workers from falling during work.

[0048] The detachable protective fence assembly 800 includes several sleeves 810, a fence frame 820, and several columns 830. In conjunction with them, the outward ends of the cross bars 510 in the two sets of retractable cross arm assemblies 500 are provided with threaded holes, and the top of the construction platform 300 is provided with several threaded holes. The threaded holes on the outward ends of the cross bars 510 and the threaded holes on the top of the construction platform 300 are arranged into a rectangular frame shape corresponding to the fence frame 820. Several sleeves 810 are provided with external threads on the outside, and several sleeves 810 are threadedly connected to the threaded holes in sequence. The sleeves 810 can limit the movement of the springboard 600 toward the width direction of the track 100, thereby preventing the springboard 600 from falling.

[0049] In this way, the springboard 600 is placed on the plurality of crossbars 510. The movement of the springboard 600 in the length direction of the track 100 is restricted by the blocking posts 610 and the movement of the springboard 600 in the width direction of the track is restricted by the plurality of shaft sleeves 810, so that the springboard 600 will not have the risk of falling off.

[0050] Furthermore, a plurality of upright posts 830 are connected to the bottom of the fence frame 820 , and the plurality of upright posts 830 correspond to the plurality of shaft sleeves 810 . By inserting the plurality of upright posts 830 into the plurality of shaft sleeves 810 , the fence frame 820 is fixed.

[0051] The following examples illustrate the working process of the present invention in a specific application. It should be noted that the content described below is only a specific application example of the present solution and does not constitute a limitation to the present solution.

[0052] The first step is to start: open the control box 700, control the caliper 230 to unlock the drive wheel 220, and the control box 700 controls the drive wheel 220 to rotate so that the mobile chassis 200 moves to the working point. Then the control box 700 controls the caliper 230 to lock the drive wheel 220, so that the mobile chassis 200 stops.

[0053] The second extension: use the control box 700 to control the two sets of retractable cross arm components 500 to unfold, and close the control box 700.

[0054] The third step is to lay the planks: climb up to the construction platform 300 via the ladder 400 and fix the springboard 600 to the crossbar 510 to form a construction expansion platform and increase the working area of ​​the tooling vehicle.

[0055] The fourth step is protection: installing the detachable protective fence assembly 800 to the construction platform 300 and the outside of the expansion platform to ensure construction safety.
