Description
Technical Field
[0001] The utility model relates to the technical field of shield construction battery vehicles, and more specifically to a parking device for shield construction battery vehicles. Background Art
[0002] Shield machines are widely used in the construction of urban subway tunnels. As large-scale mechanical equipment for underground construction, during the excavation process of the shield machine, the shield machine cutter head scrapes and breaks the soil layer in front through cutting rollers, and then uses pipe segments to support the tunnel and discharge the debris. The shield machine pushes itself forward by pushing the rear pipe segments, thereby realizing the excavation work of the shield machine.
[0003] The shield construction battery vehicle is a special transport vehicle used in the shield construction process of underground tunnels, mainly used to transport various materials in the tunnel. For the task of discharging the earth and soil from the tunnel of the earth pressure balance shield machine, the shield battery vehicle is often required to transport the earth and soil from the tunnel to the wellhead via the track.
[0004] At present, the shield machine battery car mainly uses brake shoe brakes for parking. The brake shoe device can park the vehicle while the vehicle is moving, and after the driver cuts off the power and stops the vehicle, the parking device will automatically engage the brake shoe to form a brake to achieve parking. Since the shield machine battery car has a large deadweight when transporting slag, long-term heavy load braking wear can easily lead to brake shoe failure. When parking between the battery wheel and the track, especially when parking at a location with a large slope, the car often slips. The braking effect is poor, and the protective measures are insufficient. There are great safety hazards, which affect the normal shield construction and worker safety.
[0005] Therefore, it is necessary to provide a parking device for a shield construction battery vehicle to solve the above technical problems. Utility Model Content
[0006] The utility model aims to provide a parking device for a shield construction battery vehicle to solve the above technical problems.
[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0016] Furthermore, a groove is provided in the movable seat, a plurality of rotating rods are rotatably provided on the inner wall of the groove, a roller is provided on the rotating rod, and the roller is rollingly fitted with the inner wall of the guide rail.
[0017] Furthermore, a limiting slide bar is provided between the support and the fixed seat, and the limiting slide bar slides through the movable seat.
[0018] Furthermore, the pressing mechanism comprises:
[0019] A rotating shaft, rotatably arranged on the inner wall of the parking shoe, and a roller and a gear are arranged on the rotating shaft;
[0020] A tooth plate is slidably arranged on the inner wall of the parking shoe, and the tooth plate is meshed with the gear, and a holding block is arranged at the lower end of the tooth plate.

[0022] Furthermore, rubber pads are provided inside the parking shoe and at the bottom of the holding block.
[0023] Compared with the prior art, the beneficial effects of the present invention are:
[0024] 1. In this scheme, when the battery vehicle is in the parking state, the driving mechanism will drive the moving seat to move horizontally at the same time. Through the cooperation of the second connecting rod and the first connecting rod, the parking shoe is driven to move down to contact and press the battery vehicle track, which can further realize the effective parking of the battery vehicle on the battery vehicle track. It can greatly prevent the battery vehicle from slipping when the brake shoe fails to hold, and the braking effect is significantly improved. In particular, the braking performance of the battery vehicle can be better improved in locations with larger slopes. The parking effect is good and the protective measures are perfect, which can effectively ensure the normal progress of the shield construction and improve the safety factor of the staff.
[0025] 2. In this solution, after being used for a period of time or when the battery vehicle is on a large slope, if the parking shoe also slides in the parking state, the upper end surface of the battery vehicle track can be further compressed by the pressing mechanism.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
[0041] See also Figure 1-8A parking device for a battery vehicle for shield construction includes a battery vehicle track 1 and a battery vehicle arranged above it, and also includes: a fixed seat 2 and a bracket 3, both of which are arranged at the bottom of the battery vehicle; a first connecting rod 4, one end of which is hinged to the bracket 3, and the other end of which is hinged to a parking shoe 5 adapted to the battery vehicle track 1, a second connecting rod 6 is hinged to the parking shoe 5, and the other end of the second connecting rod 6 is hinged to a moving seat 7; a driving mechanism 8, which is arranged at the bottom of the battery vehicle and is used to drive the moving seat 7 to move horizontally; a holding mechanism 9, which is arranged on the parking shoe 5 and has two.
[0042] When the battery car driver stops, the driver leaves the seat or turns off the key switch, the brake shoe of the battery car itself engages the battery car track 1 to form a brake, and at this time the driving mechanism 8 is started, and the driving mechanism 8 drives the moving seat 7 to move horizontally, so that the battery car can be stopped. Figure 1-2 For example, at this time, the driving mechanism 8 will drive the moving seat 7 to move to the left, and the moving seat 7 will drive the second connecting rod 6 to move, and through the cooperation with the first connecting rod 4, drive the parking shoe 5 to move downward, and finally make the parking shoe 5 contact and press the battery car track 1, so that the parking shoe 5 can further realize the effective parking of the battery car on the battery car track 1, which can greatly prevent the battery car from slipping when the brake shoe fails to hold, and the braking effect is significantly improved, especially in the position with a larger slope, which can better improve the braking performance of the battery car, and use the first connecting rod 4, the second connecting rod 6 and the battery car to form a triangular support, so that the parking effect is good, the protective measures are perfect, and the potential safety hazards are reduced, which can effectively ensure the normal progress of the shield construction and improve the safety factor of the staff.
[0043] When the electric vehicle driver enters the seat and turns on the key switch, the driving mechanism 8 will start to drive the movable seat 7 to move to the right, and the cooperation of the second connecting rod 6 and the first connecting rod 4 will drive the parking shoe 5 to move up, so that the parking shoe 5 is retracted and separated from the electric vehicle track 1, and then the electric vehicle can drive normally and complete the driving operation, the state conversion is smooth, and the actual operation effect is good.
[0044] When in the parking state, the parking shoe 5 contacts and presses the battery vehicle track 1. After being used for a period of time or when the battery vehicle is on a large slope, if the parking shoe 5 also slides, the upper end surface of the battery vehicle track 1 can be further pressed by the pressing mechanism 9. When the sliding force of the parking shoe 5 is greater, the pressing force of the pressing mechanism 9 also becomes greater, which has a good insurance effect and can greatly avoid the parking shoe 5 from slipping on the battery vehicle track 1 due to a large displacement, further improving the parking performance of the battery vehicle, having strong practicality, greatly improving the parking safety, and having a good use effect.
[0045] The lengths of the second connecting rod 6 and the first connecting rod 4 can be selected according to the length of the battery car, the distance between the battery car and the battery car track 1, the battery car wheel and other parameters to meet the requirements of the on-site shield machine battery car use, and have a wide range of applications.
[0046] In this embodiment, preferably, please refer to Figure 1-3 The driving mechanism 8 includes: a guide rail 81, a support 82 and a driving member 83, all of which are arranged at the bottom of the battery vehicle. The movable seat 7 is slidably arranged in the guide rail 81; a screw rod 84 is rotatably arranged between the support 82 and the fixed seat 2, the output end of the driving member 83 is connected to one end of the screw rod 84, and the movable seat 7 is threadedly connected to the screw rod 84. The driving member 83 in this application adopts a servo motor. When the driving member 83 is started, the screw rod 84 will rotate. The guide rail 81 restricts the rotation of the movable seat 7, so the rotation of the screw rod 84 will drive the movable seat 7 to move horizontally along the guide rail 81, so that Figure 1-3 For example, when the battery car driver parks, the driving member 83 drives the screw rod 84 to rotate, so that the movable seat 7 moves to the left; and when the battery car driver sits in the seat and prepares to drive, the driving member 83 drives the screw rod 84 to rotate in the opposite direction, so that the movable seat 7 moves to the right. The guide rail 81 is provided with two left and right limit switches to prevent the movable seat 7 from moving too much.
[0047] A gravity sensor is provided at the bottom of the seat of the battery vehicle, and the range of gravity is adjustable. The start signal is fed back to the driving member 83 through the change of the gravity sensor or the switch of the key.
[0048] In this embodiment, preferably, please refer to Figure 3-5 A groove 10 is provided in the movable seat 7, and a plurality of rotating rods 11 are rotatably provided on the inner wall of the groove 10. A roller 12 is provided on the rotating rod 11, and the roller 12 rolls and fits with the inner wall of the guide rail 81. When the screw rod 84 rotates and drives the movable seat 7 to move left and right, the movable seat 7 drives the roller 12 to roll along the inner wall of the guide rail 81, thereby improving the stability of the movable seat 7 when moving, and further improving the supporting stability of the second connecting rod 6, the first connecting rod 4 and the parking shoe 5.
[0049] In this embodiment, preferably, please refer to Figure 3-5 A limit slide bar 13 is also provided between the pillar 82 and the fixed seat 2, and the limit slide bar 13 slides through the movable seat 7. When the movable seat 7 moves, it slides along the limit slide bar 13, and the limit slide bar 13 can make the movable seat 7 move more stably, which greatly avoids shaking during the movement of the movable seat 7.
[0050] In this embodiment, preferably, please refer to Figure 1-2 and Figure 7-8The pressing mechanism 9 includes: a rotating shaft 91, which is rotatably arranged on the inner wall of the parking shoe 5, and a roller 92 and a gear 93 are arranged on the rotating shaft 91; a tooth plate 94, which is slidably arranged on the inner wall of the parking shoe 5, and the tooth plate 94 is meshed with the gear 93, and a pressing block 95 is arranged at the lower end of the tooth plate 94. When the parking shoe 5 slides, Figure 7 For example, when the parking shoe 5 slides to the left, the state of the left holding mechanism 9 is: the roller 92 on the left will rotate counterclockwise, and the roller 92 will drive the rotating shaft 91 and the gear 93 to rotate counterclockwise, and the gear 93 will drive the tooth plate 94 and the holding block 95 to move downward, so that the upper end surface of the battery vehicle track 1 can be pressed by the holding block 95; at this time, the holding block 95 in the right holding mechanism 9 is in an ascending state. When the parking shoe 5 slides to the right, it can be known that the holding block 95 in the left holding mechanism 9 is in an ascending state, and the holding block 95 in the right holding mechanism 9 is in a descending and pressing state, which can significantly improve the parking performance of the battery vehicle and improve safety.

The elastic member 16 in the present application is a spring or a combination of a spring and a damper. The elastic member 16, the sliding block 15 and the support rod 17 support the tooth plate 94 and the holding block 95, so that the parking shoe 5 is in a normal state, and the holding block 95 does not move or shake arbitrarily. When the tooth plate 94 moves downward, the support rod 17 drives the sliding block 15 to slide along the slide groove 14, and compresses the elastic member 16. When the tooth plate 94 is not rotated and moved downward by the gear 93, the elastic member 16 will restore the tooth plate 94 holding block 95 to a normal natural state.
