[0002] With the continuous improvement of infrastructure construction and the rapid growth of railway and subway mileage, the length of railway and subway tunnels is also increasing sharply. During the tunnel construction process, it is necessary to carry out marking, drilling and equipment installation on the inner wall of the tunnel. However, there are cable trenches and drainage trenches on both sides of the tunnel, which require special support for construction. However, the movement of the support is very inconvenient and unstable, resulting in low efficiency of tunnel construction. Conventional ladder vehicles cannot approach the tunnel side walls that need to be constructed due to the obstruction of cable trenches and drainage trenches. Utility Model Content

[0003] Based on this, it is necessary to provide a tunnel side wall operation vehicle that is easy to move and has high operation safety.

[0004] A tunnel sidewall working vehicle, comprising a traveling mechanism; the traveling mechanism comprises a base; a first traveling wheel, a first supporting wheel and a second supporting wheel are mounted at the bottom of the base; the first traveling wheel is used for traveling in a ground ditch of a tunnel; the first supporting wheel and the second supporting wheel are arranged facing each other and are used for respectively contacting an inner side wall and an outer side wall of the ground ditch away from the tunnel sidewall when the first traveling wheel travels in the ground ditch;

[0005] A bracket is fixed on the base and is arranged obliquely relative to the tunnel side wall; a working platform is arranged at one end of the bracket away from the base; and the side surface of the working platform is provided with the side wall support wheel in contact with the tunnel side wall.

[0006] In one embodiment, a first mounting frame and a second mounting frame are provided at the bottom of the base; the first mounting frame and the second mounting frame are spaced apart in a direction perpendicular to the walking direction of the walking mechanism, and the first mounting frame is located on the side of the second mounting frame facing the side wall support wheel; the first walking wheel is installed at the bottom end of the first mounting frame; the first support wheel is installed transversely on the side of the first mounting frame facing the second mounting frame; and the second support wheel is installed transversely on the side of the second mounting frame facing the first mounting frame.

[0007] In one embodiment, the first mounting frame includes a supporting straight rod and a reinforcing rib rod; the supporting straight rod is vertically arranged, and one end is fixedly connected to the bottom of the base, and the other end is equipped with the first walking wheel; the reinforcing rib rod is inclined, and both ends are respectively fixedly connected to the supporting straight rod and the bottom end of the base; the second supporting wheel is installed on the side of the supporting straight rod facing the second mounting frame.

[0008] In one embodiment, the second mounting frame is a bent rod with both ends bent along a side toward the first mounting frame; one end of the second mounting frame is fixedly connected to the base, and the other end is equipped with the second support wheel arranged laterally.

[0009] In one embodiment, the walking mechanism also includes a third support wheel; the third support wheel is transversely installed at the bottom of the base and is used to contact the inner wall of the ground ditch close to the tunnel side wall when the first walking wheel walks in the ground ditch.

[0010] In one of the embodiments, in a direction perpendicular to the walking direction of the walking mechanism, the first support wheel is flush with the third support wheel.

[0012] When the tunnel side wall working vehicle is performing side wall work in the tunnel, the first traveling wheel can drive the tunnel side wall working vehicle to move in the ground ditch in the tunnel, so as to facilitate the moving operation of the tunnel side wall working vehicle in the tunnel. When the first traveling wheel is located in the ground ditch, the side wall supporting wheel is supported on the tunnel side wall to provide lateral support for the working platform, and at the same time, the working platform can be ensured to move smoothly on the tunnel side wall during the movement of the tunnel side wall working vehicle. When the first walking wheel is located in the ground ditch, the first support wheel and the second support wheel are in contact with the inner wall and the outer wall of the ground ditch away from the tunnel side wall respectively. During the construction process, if the base of the tunnel side wall work vehicle has a tendency to slide in the direction away from the tunnel side wall, the first support wheel has a force on the base in the direction away from the tunnel side wall, so it plays a lateral support role on the base to reduce the probability of the tunnel side wall work vehicle tipping inward; if the work platform has a tendency to flip in the direction away from the tunnel side wall, the second support wheel has a support force on the base in the direction toward the tunnel side wall, so it plays a supporting role on the base to reduce the probability of the tunnel side wall work vehicle tipping outward.

[0021] Figure 1 The structure of a tunnel side wall working vehicle in one embodiment of the utility model is shown. For the convenience of description, the accompanying drawings only show structures related to the utility model.

[0022] See also Figure 1 and Figure 2 In a preferred embodiment of the utility model, the tunnel side wall work vehicle 100 is used to assist construction personnel in drilling, equipment installation, marking and other operations on the side wall in the tunnel. The tunnel side wall work vehicle 100 includes a traveling mechanism 110. The traveling mechanism 110 includes a base 111. A first traveling wheel 112, a first supporting wheel 113 and a second supporting wheel 114 are installed at the bottom of the base 111. The first traveling wheel 112 is used to travel in the ground ditch 20 of the tunnel. The first supporting wheel 113 and the second supporting wheel 114 are arranged opposite to each other and are used to contact the inner side wall and the outer side wall of the ground ditch 20 away from the tunnel side wall 10 when the first traveling wheel 112 travels in the ground ditch 20. A bracket 120 is fixed on the base 111 and is arranged obliquely relative to the tunnel side wall 10. A working platform 130 is arranged at one end of the bracket 120 away from the base 111. A side wall supporting wheel 140 that contacts the tunnel side wall 10 is arranged on the side of the working platform 130.

[0023] The ground ditch 20 in the tunnel refers to a ditch formed on the ground in the tunnel, such as a cable ditch and a drainage ditch.

[0024] When the tunnel sidewall working vehicle 100 is performing sidewall working in the tunnel, the first traveling wheel 112 can drive the tunnel sidewall working vehicle 100 to move in the ground ditch 20 in the tunnel, so as to facilitate the moving working of the tunnel sidewall working vehicle 100 in the tunnel.

[0025] When the first traveling wheel 112 is located in the ground ditch 20, the side wall support wheel 140 is supported on the tunnel side wall 10 to provide lateral support for the working platform 130. At the same time, the working platform 130 can be ensured to move smoothly on the tunnel side wall 10 during the walking process of the tunnel side wall working vehicle 100.

[0026] When the first traveling wheel 112 is located in the ground ditch 20 , the first supporting wheel 113 and the second supporting wheel 114 are in contact with the inner wall and the outer wall of the ground ditch 20 away from the tunnel side wall 10 , respectively. During the construction process, if the base 111 of the tunnel side wall work vehicle 100 has a tendency to slide away from the tunnel side wall 10, the inner wall of the ground ditch 20 away from the tunnel side wall 10 applies a force toward the tunnel side wall 10 to the first support wheel 113, so the first support wheel 113 plays a lateral supporting role on the base 111, thereby reducing the probability of the tunnel side wall work vehicle 100 tipping inward; if the work platform 130 has a tendency to flip in the direction away from the tunnel side wall 10, the outer wall of the ground ditch 20 away from the tunnel side wall 10 applies a force away from the tunnel side wall 10 to the second support wheel 114, so the second support wheel 114 plays a lateral supporting role on the base 111, thereby reducing the probability of the tunnel side wall work vehicle 100 tipping outward. Therefore, the arrangement of the first support wheel 113, the second support wheel 114 and the side wall support wheel 140 not only improves the stability of the tunnel side wall working vehicle 100 during construction operations in the tunnel to improve safety of use, but also ensures that the tunnel side wall working vehicle 100 can move smoothly in the tunnel, thereby improving convenience of use.

[0027] In some embodiments, a first mounting frame 115 and a second mounting frame 116 are provided at the bottom of the base 111. The first mounting frame 115 and the second mounting frame 116 can be fixed to the bottom of the base 111 by welding, screwing, etc. The first mounting frame 115 and the second mounting frame 116 are arranged at intervals in a direction perpendicular to the walking direction of the walking mechanism 110, and the first mounting frame 115 is located on the side of the second mounting frame 116 facing the sidewall support wheel 140. The first walking wheel 112 is installed at the bottom end of the first mounting frame 115. The first support wheel 113 is installed transversely on the side of the first mounting frame 115 facing the second mounting frame 116. The second support wheel 114 is installed transversely on the side of the second mounting frame 116 facing the first mounting frame 115.

[0028] The arrangement of the first mounting frame 115 and the second mounting frame 116 not only facilitates the installation of the first traveling wheel 112, the first supporting wheel 113 and the second supporting wheel 114, but also the first mounting frame 115 can avoid interference with the inner wall of the ground ditch 20 while ensuring that the first traveling wheel 112 and the first supporting wheel 113 enter the ground ditch 20, thereby improving the reliability of the tunnel side wall working vehicle 100.

[0029] Further, in some embodiments, the first mounting frame 115 includes a support rod 115 and a reinforcing rib rod 1152. The support rod 115 is vertically arranged, and one end is fixedly connected to the bottom of the base 111, and the other end is installed with the first walking wheel 112. The reinforcing rib rod 1152 is inclined, and both ends are fixedly connected to the support rod 115 and the bottom end of the base 111. The second support wheel 114 is installed on the side of the support rod 115 facing the second mounting frame 116.

[0030] In this way, the support straight rod 115 is mainly used for the installation and support of the first walking wheel 112 and the first supporting wheel 113. The reinforcing rib rod 1152 forms a triangular structure with the support straight rod 115 and the base 111 respectively, which mainly plays a reinforcing role. Therefore, the first mounting frame 115 is set as the support straight rod 115 and the reinforcing rib rod 1152, which not only makes the structure of the first mounting frame 115 simple, but also makes the first mounting frame 115 have higher structural stability and supporting strength.

[0031] Further, in some embodiments, the second mounting frame 116 is a bending rod with both ends bent along a side toward the first mounting frame 115. One end of the second mounting frame 116 is fixedly connected to the base 111, and the other end is installed with a transversely arranged second support wheel 114. Specifically, the other end of the second mounting frame 116 is located below the base 111. Thus, the second mounting frame 116 is composed of a single bending rod, which can be a hollow rod such as a pipe fitting, or a solid rod, so that the structure of the second mounting frame 116 is simplified while meeting the installation requirements and use requirements of the second support wheel 114.

[0032] In some embodiments, the walking mechanism 110 further includes a third support wheel 117. The third support wheel 117 is transversely mounted at the bottom of the base 111 and is used to contact the inner wall of the ground ditch 20 close to the tunnel sidewall 10 when the first walking wheel 112 walks in the ground ditch 20.

[0033] In this way, when the first running wheel 112 is located in the ground ditch 20, the first support wheel 113 and the third support wheel 117 are in contact with the two inner side walls of the ground ditch 20 respectively, so as to reduce the probability of the first running wheel 112 running off when running in the ground ditch 20. At the same time, when the tunnel side wall working vehicle 100 is working in the tunnel, if the working platform 130 has a tendency to flip in the direction away from the tunnel side wall 10, the inner side wall of the ground ditch 20 close to the tunnel side wall 10 exerts a force on the third support wheel 117 in the direction away from the tunnel side wall 10, so the third support wheel 117 plays a lateral supporting role on the base 111, further reducing the probability of the tunnel side wall working vehicle 100 turning to the outer side wall. Therefore, the provision of the third support wheel 117 further improves the stability of the tunnel side wall working vehicle 100 in the tunnel, and also makes it safer to use.

[0034] Specifically, when the walking mechanism 110 further includes a first mounting frame 115 and a second mounting frame 116 , the third supporting wheel 117 is transversely mounted on a side of the first mounting frame 115 facing away from the second mounting frame 116 .

[0035] Of course, in other embodiments, the third supporting wheel 117 may also be installed on other mounting structures different from the first mounting frame 115 and the second mounting frame 116 .

[0036] Further, in some embodiments, in a direction perpendicular to the traveling direction of the traveling mechanism 110, the first supporting wheel 113 is flush with the third supporting wheel 117. That is, the first supporting wheel 113 and the third supporting wheel 117 are at the same height, and when the first supporting wheel 113 and the third supporting wheel 117 are both mounted on the first mounting frame 115, the lateral supporting forces of the first supporting wheel 113 and the third supporting wheel 117 on the first mounting frame 115 are located on the same horizontal plane, so that the tunnel side wall working vehicle 100 moves more smoothly in the ground ditch 20.

[0037] In some embodiments, a second running wheel 118 is further provided at the bottom of the base 111. The second running wheel 118 is located between the first support wheel 113 and the second support wheel 114. The second running wheel 118 is located at a height higher than the first support wheel 113 and the second support wheel 114, respectively, and is configured to be able to run on the top surface of the side of the ground ditch 20 away from the tunnel side wall 10 when the first running wheel 112 runs in the ground ditch 20.

[0038] In this way, the second traveling wheel 118 has the same function as the first traveling wheel 112, both of which are used to drive the tunnel side wall working vehicle 100 to move in the tunnel, and at the same time also support the base 111, further improving the stability of the tunnel side wall working vehicle 100 moving in the tunnel.

[0039] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
