Description

Technical Field

[0001] The utility model belongs to the field of tunnel construction, in particular to a tunnel truss trolley moving device. Background Art

[0002] The rapid development of the economy has greatly promoted the improvement of various infrastructures. At present, with the increasing number of new energy power generation, the significance of pumped storage is becoming more and more significant. At present, the construction of pumped storage tunnels is relatively common. Tunnels are spaces formed by digging soil or rocks under the surface. In general, tunnel construction requires different forms of work trolleys according to different construction methods to meet the needs of construction; the common outstanding disadvantages of commonly used work trolleys are: first, the trolleys are limited in transportation, movement, and adjustment in the tunnel, and they are large in size, inconvenient to transport, and difficult to move; second, these work trolleys have poor general performance, and they need to be modified when the tunnel section changes or the construction process changes, and cannot be reused, so they have poor adaptability; third, there is a lack of safety protection system. Once the roof collapses or blocks fall during use, it cannot effectively protect the safety of construction personnel. In summary, providing a multifunctional work trolley for tunnel construction has become a problem that needs to be solved by technicians in this field.

[0003] Traditionally, when constructing, maintaining and repairing such tunnel structures, a vehicle with a ladder-type scaffolding that can be folded to adjust the height is required. However, since conventional construction using vehicles requires full control of personnel and vehicles passing through the tunnel during the day and night, the use of tunnels as national infrastructure is restricted and can no longer meet the current high-intensity construction requirements. It is time-consuming and labor-intensive, with low construction efficiency, inconvenient on-site management, and poor economic efficiency.

[0004] In addition, considering the frequency of regular tunnel construction and the trend of increasing new tunnels, a temporary construction system is needed to improve the work and construction efficiency of tunnel maintenance and repair. In particular, it is necessary to develop an operating device that can realize real-time passage of people and vehicles and facilitate operations. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a tunnel truss trolley moving device, which is convenient for daily construction and maintenance of the tunnel and eliminates interference of structures installed inside the tunnel.

[0006] The utility model adopts the following technical solutions to solve the above problems:

[0007] A tunnel truss trolley moving device comprises a horizontal truss member and a vertical truss member of a single-layer truss structure, wherein the vertical truss member is vertically connected to the bottom of both ends of the horizontal truss member, a reinforced truss unit is provided at the connection between the horizontal truss member and the vertical truss member, and the reinforced truss unit comprises a first reinforced truss member and a second reinforced truss member, and a truss member moving component is provided at the bottom of the vertical truss member.

[0010] Furthermore, the fixing device comprises an H-shaped steel arranged perpendicularly to the vertical truss member, and the upper flange and the lower flange of the H-shaped steel are respectively provided with a plurality of upper steel pipes and a plurality of lower steel pipes.

[0011] Furthermore, the upper steel pipe is detachably connected to the lower end of the vertical truss member, and the lower steel pipe is detachably connected to the rolling device.

[0012] Furthermore, a plurality of fastening holes are provided on the side of the vertical truss member, and a working device unit is movably connected through the fastening holes, and the working device unit is hinged with a supporting plate protruding for supporting the operator's load.

[0013] Furthermore, the working device unit includes a frame, a hook component arranged on one side of the frame, and a fixing component arranged at the lower end of the frame, and the hook component is matched and connected with the fastening hole.

[0014] Furthermore, the support plate and the frame are integrally formed, and the frame is hinged to the fixing member and fixedly supported at the lower end of the frame.

[0015] Furthermore, the horizontal truss member includes a plurality of unit trusses, and the plurality of unit trusses are spliced ​​in sequence through a fixing mechanism.

Compared with the past, it is easier and can reduce the workload;

[0019] 2. The general truss structure is a three-dimensional truss assembled from three dimensions, namely, top, bottom, left and right, while the horizontal truss member of the utility model is a plane main member assembled from a plane truss. Therefore, the utility model can solve the problem that the distance between the building limit line and the upper devices such as the ventilator in the tunnel is narrow and it is difficult for workers to move;

The reinforcement truss unit 150 can be formed to be thinner than the horizontal truss member 110 and the vertical truss member 130. The reinforcement truss unit 150 includes a first reinforcement truss member 151 and a second reinforcement truss member 153. A truss member moving part 180 is provided at the bottom of the vertical truss member 130, so that the horizontal truss member 110 and the vertical truss member 130 can be moved in the longitudinal direction of the tunnel, so that the parts that need construction and maintenance can be easily constructed and repaired.

A working scaffold (not shown in the figure) can be installed on the upper part of the horizontal truss member 110 so that operators can work.

[0037] like Figure 1 , Figure 2 As shown, the working device unit 170 is detachably connected to the vertical truss member 130, and a support plate 171 for supporting an operator's load is hingedly protruded.

[0038] like Figure 3 , Figure 4 As shown, Figure 3 The working device unit 170 is disclosed in a state of being deployed. Figure 4A drawing is disclosed in which the working device unit 170 is configured into multiple shapes to form a staircase in a folded state. A plurality of fastening holes 131 are provided on the side of the vertical truss member 130, and the working device unit 170 is movably connected through the fastening holes 131. The working device unit 170 includes a frame 175, a hook member 173 provided on one side of the frame 175, and a fixing member 176 provided at the lower end of the frame 175. The hook member 173 is connected to the fastening hole 131 in a coordinated manner. The working device unit 170 is hinged with a support plate 171 protruding for supporting the operator's load. The support plate 171 is integrally formed with the frame 175. The frame 175 is hinged to the fixing member 176 and fixedly supported at the lower end of the frame 175, so that the support plate 171 is supported by contacting the bottom inside the tunnel, thereby maintaining a horizontal state.

[0039] like Figure 5 As shown, the truss member moving part 180 includes a fixing device 181 connected to the lower end of the vertical truss member 130, and a rolling device 185 rotatably mounted at the lower end of the fixing device 181. ， The fixing device 181 includes an H-shaped steel 182 vertically arranged with respect to the vertical truss member 130. The upper flange and the lower flange of the H-shaped steel 182 are respectively provided with a plurality of upper steel pipes 183 and lower steel pipes 184. The upper steel pipe 183 is detachably connected to the lower end of the vertical truss member 130, and the lower steel pipe 184 is detachably connected to the rolling device 185. The H-shaped steel 182 can ensure the structural stability of the truss member moving part 180, and facilitate its connection with the vertical truss member 130, and also facilitate the connection of the rolling device 185, so that the installation of the rolling device 185 is more stable and convenient.

[0040] According to a tunnel truss trolley moving device provided by the utility model, it is installed in the tunnel and the construction limit line area of ​​the tunnel, while avoiding interference from devices installed on the upper part or side of the tunnel (such as fans or road signs); in this case, the construction limit refers to a certain space limit set on roads, etc. in order not to affect the driving of vehicles, to prevent buildings from entering the limit range, which is to solve the problem of construction difficulties caused by the narrow space between facilities.

[0041] According to a tunnel truss trolley moving device of the utility model, a general truss structure is a three-dimensional truss assembled from three dimensions, namely, top, bottom, left and right, while the horizontal truss member 110 of the utility model is a plane main member assembled from plane trusses. Therefore, the utility model can solve the problem that the distance between the building limit line and the upper devices such as the ventilator in the tunnel is narrow, making it difficult for workers to move; at this time, a working pedal is installed on the upper part of the horizontal truss member 110 to enable workers to work safely.

[0042] During operation, the vertical truss member 130 can be vertically connected to the horizontal truss member 110 and can be set as a single layer to avoid installation on the side of the tunnel; the vertical truss member 130 is made of a single-layer assembled flat truss like the horizontal truss member 110, and facilities are installed on the side, such as road signs or safety facilities installed in the tunnel, and it can achieve work by installing the structure without interference.

[0043] The horizontal truss members 110 and the vertical truss members 130 can be coupled to be perpendicular to each other, and each truss member can be connected by pins instead of welding to facilitate assembly and disassembly during tunnel construction. The assembly and disassembly process of the horizontal truss members 110 and the vertical truss members 130 can be carried out in an open space outside the tunnel, and can be fully assembled and placed in a space where tunnel construction is required, in order to prevent vehicles from being temporarily controlled due to assembly and disassembly work.

[0044] The reinforcement truss unit 150 may be formed to protrude from the corner portion to reinforce the corner where the horizontal truss member 110 and the vertical truss member 130 meet. Since the portion where the horizontal truss member 110 and the vertical truss member 130 intersect in the structure bears the largest load, a reinforcement truss unit 150 and a corner are configured as a reinforcement portion. In this case, the reinforcement truss unit 150 may be formed to be thinner than the horizontal truss member 110 and the vertical truss member 130. That is, due to the reinforcement truss unit 150 50 is for reinforcing the horizontal truss member 110 and the vertical truss member 130 which are basic members of the structure, and therefore the reinforcing truss unit 150 is a truss member which is configured in consideration of the necessary load for reinforcing the edge portion; at this time, by being composed of a truss member thinner than the basic member, there is an advantage of being able to accurately reinforce by the required load; furthermore, when workers are working in a tunnel truss trolley moving device, the reinforcing truss unit 150 is coupled to the outer side protruding to the corner, and it can become a working railing for the workers' safety.

[0045] On the other hand, in the reinforced truss unit 150, the first reinforced truss member 151 is coupled to the inner side of the corner where the vertical truss member 130 and the horizontal truss member 110 are located, and the vertical member and the horizontal member can be configured to include a second reinforced truss member 153, which is coupled to the outer side of the corner where the members are connected; therefore, the right-angle connection between the horizontal truss member 110 and the vertical truss member 130 can fully resist the load burden caused by the stress concentration in the angled part of the corner, and the second reinforced truss member 153 is connected to the corner part, which can serve as a working handrail to ensure the safety of operators during tunnel maintenance work, thereby improving work safety.

[0046] The working device unit 170 is detachably coupled to the vertical truss member 130. When there is no work or the truss structure is moved, the working device unit 170 can be separated to eliminate interference from the side installation in the tunnel. The working device unit 170 can be hingedly connected to the vertical truss member 130, and a support plate 171 for supporting the operator's load protrudes. When there is no maintenance work or moving the truss structure in the tunnel, the working device unit 170 can be expanded to eliminate interference from the side devices and reduce the volume of the structure; on the other hand, when there is maintenance work in the tunnel, the support plate 171 can be horizontally made by folding the hinge part H, and the working device unit 170 can be configured as a scaffold to support the operator's load and Convenient for work; the working device unit 170 includes a hook component 173, which is installed in the fastening hole 131 on the vertical truss member 130, and the hook component 173 is located on one side, and there is also a fixing component 176, which is fixed on the frame 175 integrally formed with the support plate 171, and the frame 175 is hingedly connected to the support plate 171 so that it is in a horizontal state; the working device unit 170 can be coupled when the hook component 173 is unfolded in the vertical truss member 130. Under normal circumstances, the hook component 173 can be installed in the fastening hole 131; when working inside, the hinge H coupling part can be folded, so that the support plate 171 becomes a form of a working scaffold, such as Figure 1 As shown, the fixing member 176 can be supported by a step 11 installed below the tunnel side so that the frame 175 and the support plate 171 are in a horizontal state. At this time, the hinge part H can be equipped with a fixing device (not shown in the figure) to fix the frame 175 and the fixing member 176 when they are folded at a right angle.

[0047] The truss member moving part 180 and the fixing device 181 are connected to the lower end of the vertical truss member 130, and the rolling device 185 is rotatably installed at the lower end of the fixing device 181. The fixing device 181 can be installed at the bottom of the truss member to install the rolling device 185, and the material and shape are not limited; in this embodiment, the rolling device 185 can be set as a wheel, which is used to contact the tunnel truss structure 100 through the cloud at the bottom of the tunnel, and is not limited in form and material; the fixing device 181 is coupled to the upper surface of the H-shaped steel 182 having an upper flange, a lower flange and a web, and the upper flange and the lower end of the vertical truss member 130 are detachably installed. Its configuration may include an upper steel pipe 183, a lower steel pipe 184 connected to the lower surface of the lower flange, and the device 185 is detachably installed, and the vertical truss member 130 and the rolling device 185 can be firmly supported by the upper flange and the lower flange of the H-shaped steel 182. The vertical truss members 130 and the rolling devices 185 are detachably connected to the upper steel tubes 183 and the lower steel tubes 184 to facilitate assembly and disassembly of the truss structure.

[0048] Example 2

[0049] like Figure 6 As shown, the horizontal truss member 110 includes a plurality of unit trusses 111, and the plurality of unit trusses 111 are sequentially spliced ​​by a fixing mechanism, and the fixing mechanism includes an adjustment hole 113 provided on the horizontal truss member 110 and a fixing pin 114 passing through the adjustment hole 113, and other technical features are the same as those of Example 1.

[0050] During operation, since the length of the tunnel truss trolley moving device is configured to be adjustable as described above, the device can be easily operated even if the width of the tunnel is variable, and maintenance work on tunnels of various sizes can be completed using one tunnel truss structure 100. In addition, since the length can be adjusted in the longitudinal direction of the tunnel, the tunnel truss structure 100 can be stopped in the case of a long tunnel, and the length of the maintenance work can be increased in the stopped state, thereby shortening the maintenance length.

[0051] Specifically, the unit trusses 111 are fixed by a plurality of length adjustment holes 113, which are formed at predetermined intervals in the longitudinal direction of the horizontal truss member 110, and it can be configured to include a fixing pin 114 for coupling and fixing a plurality of overlapping unit trusses 111; accordingly, adjacent unit trusses 111 are stacked so that the horizontal truss member 110 has a desired length, and one unit truss 111a and another unit truss 111b (after adjusting the position of the length adjustment hole 113 of 111b) can be installed and fixed with the pin 114 so that it passes through the length adjustment hole 113.

[0052] The tunnel truss structure of this embodiment according to the above configuration can facilitate tunnel construction and maintenance work while eliminating interference from structures installed in the tunnel; in addition, the horizontal truss members and vertical truss members as basic structural members are composed of single-layer flat trusses and have reinforced truss parts for reinforcing the edge parts of the members, thereby facilitating construction and forming a temporary structure with structural safety. Since the length of the truss structure is variable and can be moved after installation, this structure can be provided to cope with tunnels with a longer length or tunnels with various widths.

[0053] The above embodiments are used to describe the present invention in detail, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention.
