Description

Technical Field

[0002] In some tunnel excavation construction, drilling and blasting is the most commonly used excavation method, which is widely used in rock tunnel construction of various sizes. The most time-consuming process of this construction method is charging, and the speed of charging can determine the progress of the entire drilling and blasting construction. For various cross-section tunnel drilling and blasting operations, due to space constraints, it is difficult to achieve mechanized operations. Usually, the construction unit temporarily sets up a scaffold for construction. If the scaffold needs to be moved, it needs to be pushed by an excavator or a bulldozer. Therefore, there are defects such as high cost, difficulty in positioning, inconvenient transportation, and non-adjustable platform. Therefore, it cannot adapt well to actual working conditions and has the problem of low construction efficiency. Utility Model Content

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0039] like Figure 1 to Figure 3 As shown, a tunnel construction trolley includes a vehicle body 1, a base platform 2 and a first lifting platform 4; the base platform 2 has a first driving mechanism for driving the base platform 2 to switch between a first recovery position and a first support position; a first lifting mechanism is provided between the first lifting platform 4 and the base platform 2, and the first lifting platform 4 has a second driving mechanism for driving the first lifting platform 4 to switch between a second recovery position and a second support position. Furthermore, it also includes a first leg 3, the first leg 3 is movably connected to the base platform 2, and is used to support the base platform 2 on the ground when the base platform 2 is in the first support position, and when the base platform 2 is in the first recovery position, the first leg 3 is hidden between the vehicle body 1 and the base platform 2.

[0040] In this embodiment, the car body 1 has a displacement drive mechanism that can realize movement in the tunnel. The middle and rear ends of the car body 1 are storage parts. In the initial state, the basic platform 2, the first lifting platform 4 and other facilities are all stored in the storage part, and the storage part also has a placement position for accommodating drilling equipment and explosives, so as to facilitate actual use needs. It should be noted that in this embodiment, the corresponding equipment and explosives can also be carried by hand and boarded on each platform to complete the corresponding tunnel construction work on each platform. The car body 1 is equipped with a fixed ladder 13, so that the staff can easily go up from the ground to the storage part, so as to further walk the basic platform 2 or go up to the first lifting platform 4. It is known that the basic platform 2 and the first lifting platform 4 are stored in the storage part, that is, the basic platform 2 is located at the first recovery position, the first lifting platform 4 is located at the second recovery position, and the first recovery position is located at the lower side of the second recovery position. During specific use, the first driving mechanism is actuated to switch the basic platform 2 to the first supporting position, at which time the staff can perform the corresponding charging operation on the basic platform 2. If the basic platform 2 cannot meet the working condition requirements, the first lifting mechanism and the second driving mechanism are driven to switch the first lifting platform 4 to the second supporting position and to the working height required by the staff, at which time the staff can perform the corresponding charging operation on the first lifting platform 4. In this embodiment, the lifting mechanism is driven by a cylinder to push or pull the scissor-type bracket 5 to achieve height adjustment, and the driving mechanism is a rotating cylinder to switch the corresponding platform between the recovery position and the supporting position, and the lifting mechanism and driving mechanism described below are similar to this, and the following description will not be repeated.

[0041] Furthermore, a second lifting platform 6 is included, a second lifting mechanism is provided between the second lifting platform 6 and the first lifting platform 4, and the second lifting platform 6 has a third driving mechanism for driving the second lifting platform 6 to switch between the third recovery position and the third support position. If the first lifting platform 4 cannot meet the use requirements, the second lifting mechanism and the third driving mechanism are used to lift the second lifting platform 6 to a higher working height, and switch from the third recovery position to the third support position. It can be seen that the third recovery position is located on the upper side of the second recovery position.

[0042] In this embodiment, a second leg 7 is provided between the first lifting platform 4 and the base platform 2. One of the first lifting platform 4 and the base platform 2 is rotatably connected to the second leg 7, and the other is detachably connected to the second leg 7. Since the first lifting platform 4 is relatively long, the second support can avoid the platform shaking caused by the overlong suspension length. In this embodiment, one end of the second leg 7 is rotatably connected to the first lifting platform 4, and the other end is clamped to the base platform 2. The second leg 7 can also be connected to the first lifting platform 4 in a detachable manner. Further, the second leg 7 is a retractable leg, so that it can be adjusted according to the actual height between the first lifting platform 4 and the base platform 2 to obtain better support.

[0043] In this embodiment, a first ladder 8 is also included, and the first ladder 8 is connected to the first lifting platform 4 by being hung or rotatably connected. A second ladder 9 is also included, and the second ladder 9 is connected to the second lifting platform 6 by being hung or rotatably connected. The second ladder 9 is connected to the first lifting platform 4, and the first ladder 8 and the second ladder 9 can provide a mobile passage for the staff, so as to facilitate the staff to perform construction at an appropriate working position. In this embodiment, the first ladder 8 and the second ladder 9 are both retractable structures, thereby adapting to actual height requirements.

[0044] In order to better use this embodiment, in this embodiment, among the basic platform 2, the first lifting platform 4, and the second lifting platform 6, any one platform has a fixed part 10 and a rotating part 11, and the fixed part 10 and the rotating part 11 in the same platform are rotatably connected, and a driving mechanism is arranged between the fixed part 10 and the rotating part 11; a lifting mechanism is arranged between any two adjacent fixed parts 10. In the height direction of the vehicle body 1, the projection of the fixed part 10 of each platform is in the storage part, which can realize the auxiliary support of each platform. After the corresponding driving mechanism is actuated, the rotating part 11 moves to expand the working area at an appropriate position, so that the staff can carry out tunnel construction at a suitable position. When the rotating part 11 moves to the supporting position, the first leg 3 and the second leg 7 are used to provide supporting stability, thereby improving the construction safety of the staff.

[0045] In this embodiment, the fixed part 10 has a placement interlayer 12. When any rotating part 11 is in the hidden position, all or part of the rotating part 11 is located in the placement interlayer 12. The hidden interlayer can not only well realize the recovery and hiding of the rotating part 11, but also provide a supporting effect for the rotating part 11 when the rotating part 11 is hidden, thereby preventing the rotating part 11 from bending or even breaking in the recovery position. That is to say, when the rotating part 11 of the corresponding platform needs to return to the hidden position, the rotating part 11 rotates relative to the fixed part 10, and then part or all of the rotating part 11 is hidden in the placement interlayer 12. Since the fixed part 10 is supported at its position, the rotating part 11 is also supported by the placement interlayer 12, thereby ensuring that it maintains a good hidden posture in the non-working state, so that the rotating part 11 will not be damaged due to external forces such as shaking and vibration during the movement of the trolley, thereby ensuring the specific use effect of each platform.

[0046] Therefore, this embodiment can adapt to different sections, adjust the lifting height of each level of platform according to the section, and can also select the number of open platform layers according to the section width, so as to meet the specific tunnel construction requirements of the staff.

[0047] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
