Description

Technical Field

[0001] This utility model relates to a telescopic gantry multi-template water ditch cable trough trolley for single-line tunnels. Background Technology

[0002] In the construction of single-track railway tunnels, due to space constraints, traditional drainage ditch and cable trough trolleys have significant functional defects—construction vehicles cannot freely pass through the trolleys during construction, resulting in a disruption of the construction process: on the one hand, the trolley operation needs to be interrupted to ensure the passage of construction vehicles, and on the other hand, the passage of vehicles delays the construction progress of drainage ditch and cable troughs. Especially in scenarios where the demand for transportation of tunnel construction vehicles is frequent, the conflict between the two seriously restricts construction efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a telescopic gantry multi-template water ditch cable trough trolley for single-line tunnels, so as to solve the problem of mutual interference between construction facilities and vehicle traffic in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A telescopic gantry multi-template water ditch cable trough trolley for single-line tunnels includes two fixed gantry frames arranged opposite and symmetrically, and the two fixed gantry frames are distributed along the length of the tunnel. The two fixed gantry frames are connected together by two crossbeams parallel to the width of the tunnel. Two movable gantry frames are slidably mounted on the two crossbeams. Each movable gantry frame is connected to an upper translation cylinder between itself and the crossbeam. The upper translation cylinder can drive the movable gantry frame to slide along the direction parallel to the tunnel width, so that the passageway formed between the two movable gantry frames is greater than or equal to the construction road. Each of the fixed gantry frames is provided with two retractable fixed gantry support legs at its lower end, which are used to support the trolley at the bottom of the trench when the trolley is working or passing through. Each of the movable gantry frames is provided with two retractable walking legs at its lower end. Each walking leg is rotatably mounted with a rubber-coated wheel parallel to the tunnel length direction. One of the walking legs at the rear end is equipped with a motor reducer drive device. The transmission gear of the motor reducer drive device is coaxially connected to the corresponding rubber-coated wheel to drive the trolley to move along the tunnel length direction.

[0005] Furthermore, the two fixed gantry frames are also connected by a connecting beam parallel to the crossbeam, and the connecting beam is located between the two crossbeams. An electric hoist is installed at the lower end of the connecting beam to realize the turnover and transportation of the template.

[0006] Furthermore, each of the walking legs is equipped with a retractable anti-top leg on its outer side. A lower translation mechanism is fixedly installed at the lower end of the anti-top leg. The slider of the lower translation mechanism is connected to a lower translation cylinder. The lower translation cylinder can drive the lower translation mechanism to move along the tunnel width direction, so as to realize the fine adjustment and steering of the trolley.

[0007] Furthermore, the fixed gantry support legs, traveling support legs, and anti-top support legs are all sleeve-type telescopic structures, and each is equipped with a vertical hydraulic cylinder to drive each support leg to extend and retract vertically, thereby adjusting the trolley support height and grounding status.

[0008] Furthermore, a hydraulic pump station is fixedly installed on the outer side of one of the rear traveling outriggers to provide hydraulic power to each cylinder. The hydraulic pump station is connected to a ten-way valve operating valve through a high-pressure oil pipe. The ten-way valve operating valve is connected to the vertical cylinders of the front and rear fixed gantry outriggers, the vertical cylinders of the front and rear traveling outriggers, the vertical cylinders of the front and rear counter-support outriggers, the front and rear upper translation cylinders, and the front and rear lower translation cylinders through high-pressure oil pipes, so as to realize independent control of each mechanism.

[0009] Furthermore, a detachable cross-river support rod is provided between the two opposing walking legs.

[0010] This utility model has the following advantages: I. This utility model, by setting up a sliding movable gantry and a translational hydraulic cylinder to drive its movement, can form a vehicle passage with a width not less than the road width when needed, solving the problem of mutual interference between traditional trolley construction and vehicle passage. It can ensure the passage of engineering vehicles without interrupting construction and significantly improves construction efficiency.

[0011] II. This utility model, by setting a retractable anti-top support leg on the outside of the walking support leg, and in conjunction with the lower translation mechanism and the lower translation cylinder, can realize the fine adjustment and steering of the trolley, which is particularly suitable for tunnel curves and improves the adaptability of the trolley in complex terrain.

[0012] Third, this utility model achieves independent control of each mechanism through the ten-way valve operation valve, which is easy to operate, precise in control, and improves the convenience and reliability of construction. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Example: like Figure 1-9 As shown, a telescopic gantry multi-template water ditch cable trough trolley for single-line tunnels includes two fixed gantry frames 1 arranged opposite and symmetrically. The two fixed gantry frames 1 are distributed along the length of the tunnel and are connected to two crossbeams 2 parallel to the width of the tunnel.

[0026] Two movable gantry 3 are slidably mounted on the two crossbeams 2. Each movable gantry 3 is connected to the crossbeam 2 by an upper translation cylinder 4. The upper translation cylinder 4 can drive the movable gantry 3 to slide along the direction parallel to the tunnel width, so that the passage between the two movable gantry 3 is greater than or equal to the construction road.

[0027] Each fixed gantry 1 is equipped with two retractable fixed gantry legs 11 at its lower end, which are used to support the trolley at the bottom of the trench when the trolley is working or passing through.

[0028] Each movable gantry 3 is equipped with two retractable walking legs 31 at its lower end. Each walking leg 31 is rotatably mounted with a rubber-coated wheel 33 parallel to the tunnel length direction. One of the walking legs 31 at the rear end is equipped with a motor reducer drive device 32, whose transmission gear is coaxially connected with the corresponding rubber-coated wheel 33 to drive the trolley to move along the tunnel length direction.

[0029] The two fixed gantry frames 1 are also connected by a connecting beam 5 parallel to the crossbeam 2. The connecting beam 5 is located between the two crossbeams 2, and an electric hoist 6 is slidably installed on its lower end via a rail to realize the turnover and transportation of the template.

[0030] Each traveling outrigger 31 is equipped with a retractable anti-top outrigger 7 on its outer side. A lower translation mechanism 71 is fixedly installed at the lower end of the anti-top outrigger 7. The slider of the lower translation mechanism 71 is connected to a lower translation cylinder 72. The lower translation cylinder 72 can drive the lower translation mechanism 71 to move along the tunnel width direction, so as to realize the fine adjustment and steering of the trolley.

[0031] The fixed gantry support leg 11, the traveling support leg 31, and the anti-top support leg 7 are all sleeve-type telescopic structures, each equipped with a vertical hydraulic cylinder 8 to drive each support leg to extend and retract vertically, adjusting the trolley support height and grounding status.

[0032] A hydraulic pump station 9 is fixedly installed on the outer side of one of the rear traveling outriggers 31 to provide hydraulic power to each cylinder. The hydraulic pump station 9 is connected to a ten-way valve operating valve 10 through a high-pressure oil pipe. The ten-way valve operating valve 10 includes ten independent directional valves, which are respectively connected to the vertical cylinders 8 of the front and rear fixed gantry outriggers 11, the vertical cylinders 8 of the front and rear traveling outriggers 31, the vertical cylinders 8 of the front and rear counter-support outriggers 7, the front and rear upper translation cylinders 4, and the front and rear lower translation cylinders 72 through high-pressure oil pipes, so as to realize independent control of each mechanism.

[0033] The two opposing walking legs (31) are detachably connected to a cross-river support screw (12). The cross-river support screw (12) can enhance the connection stability between the opposing walking legs, improve the overall structural strength and safety of the trolley during transportation, and its detachable design also facilitates quick passage.

[0034] It is important to know that the trolley has two states during operation: transporting templates and placing templates. The time spent transporting templates is less.

[0035] Working principle: When positioning the template, remove the pin on one side of the cross-river support rod 12, so that the cross-river support rod 12 is parallel to the tunnel direction, so that the lower part of the movable gantry is no longer connected together. The vertical cylinder 8 is controlled by the ten-way valve operating valve 10 to extend the fixed gantry support leg 11 and retract the traveling support leg 31 to its limit. At the same time, the horizontal translation cylinder 4 is operated to drive the two movable gantry 3 to move to the sides of the road above the ditch. At this time, the fixed gantry support leg 11 supports the bottom of the ditch and no longer occupies the road, maximizing the reserved width for vehicles to pass through and ensuring that the road is passable for a long time.

[0036] When it is necessary to transport the template, first operate the upper translation cylinder 4 to drive the two movable gantry 3 to move towards the middle of the road, and extend the walking legs 31 to the limit. Then, install the cross-river support rod (12) between the two walking legs (31). At the same time, the electric hoist 6 lifts the template. When it reaches the appropriate position, the vertical cylinder 8 is controlled by the ten-way valve operating valve 10 to retract the fixed gantry legs 11 to the limit. Then, the walking legs 31 are driven by the motor reducer drive device 32 to move to the next work position and put down the template. Then, repeat the above template positioning operation to continue the trench construction. If multi-mode trenches are constructed continuously, the fixed gantry legs do not need to be extended to be positioned. The movable gantry carries the fixed gantry back and forth to lift and position the template to achieve the function of one frame for multiple modes.

[0037] When the trolley travels to the curve of the tunnel, the lower translation mechanism 71 is driven by the lower translation cylinder 72, and the extension and retraction of the anti-jacking leg 7 are coordinated to realize the flexible steering and fine adjustment of the trolley, so as to ensure the smooth operation of the trolley at the curve.

[0038] In this embodiment, the vertical cylinders 8 of the fixed gantry support leg 11 and the traveling support leg 31 are controlled by the ten-way valve operating valve 10, so that each support leg is in a different extension and retraction state, thereby switching the support body of the trolley. When the trolley is working, the time spent on the road is minimized, road passage is facilitated, and construction efficiency is improved.

[0039] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
