[0005] As a preferred solution of the present invention, the trolley also includes a construction passage arranged in the middle of the gantry for engineering traffic, and multiple construction platforms are arranged on both sides of the gantry from top to bottom.
[0006] As a preferred solution of the present invention, the transport and guide assembly also includes a hydraulic cylinder connected to the four corners of the bottom of the guide frame, the bottom of the hydraulic cylinder is correspondingly connected to the top of the door frame, and guide columns are slidably fitted on both sides of the guide frame, and the bottom of the guide columns is correspondingly connected to the top of the door frame.
[0007] As a preferred solution of the present invention, the transport guide assembly also includes a hydraulic motor installed at a corner of the slide, a driving end of the hydraulic motor is connected to a gear, and an inner side of one side of the guide frame is provided with a rack meshing with the gear.
[0008] As a preferred solution of the present invention, the transport guide assembly also includes a support frame installed on one side of the top of the slide.
[0009] As a preferred solution of the present invention, the magazine assembly further includes a weight-reducing hole formed on the magazine body, and limit pins matched with both sides of the opening end of the magazine body, and a pin hole is formed in the middle of the base.
[0010] As a preferred solution of the present invention, a transfer assembly is also included, which includes a base, a stand mounted on one side of the top of the base, and a hydraulic cylinder 2 mounted on the other side of the top of the base; Among them, a base plate 1 is installed on the top of the vertical frame, a pin column 1 adapted to the pin hole is installed on the top of the base plate 1, a base plate 2 is installed on the top of the hydraulic cylinder 2, a pin column 2 adapted to the pin hole is installed on the top of the base plate 2, one side of the base plate 2 is connected to a side arm, one end of the side arm is connected to a slide bar, the outer sliding of the slide bar is matched with a slide groove, and the slide groove is correspondingly installed on one side of the vertical frame.
[0011] A method for using a tunnel construction trolley with a guide mechanism comprises the following steps: Step 1: The pre-processed arc-shaped steel bars are sequentially loaded into the box body, and the engineering vehicle transports the arc-shaped steel bars to the tunnel construction section through the transfer assembly; Step 2: Keep the engineering vehicle aligned with the guide frame, lower the height through the hydraulic cylinder 1 until the magnetic suction cup is aligned and placed at the bottom of the magnetic suction block, and raise the height through the hydraulic cylinder 1. When it continues to rise, the flange will continue to press down the arc pressure rod. Since the highest point of the arc pressure rod is always on the inner side of the axis of the core shaft, the wrench will rotate downward with the core shaft as the center until the core shaft is driven to rotate into place, so that the magnetic suction cup magnetically attracts the magnetic suction block, and the box body together with the arc-shaped steel bar sits on the magnetic suction block and remains stable. After the transfer assembly is separated from the pin hole, withdraw from the construction section and carry out the transportation of the next fully filled magazine assembly; Step 3: The slide moves to the front end of the guide frame. After adjusting the height, the worker takes out the arc-shaped steel bars and places them on the support frame, while bundling them. After completion, the slide moves to the rear end and releases and bundles the arc-shaped steel bars in turn until the construction section is completed, thus reducing the labor intensity of manpower by relying on mechanical assistance. Step 4, the trolley moves to the next construction section, the engineering vehicle enters again, and step 2 is performed in reverse to unload the empty magazine assembly onto pin 2. At the same time, the spring releases its elastic force, the magnetic suction cup releases its magnetic suction effect, and the engineering vehicle retreats a certain distance, so that the empty magazine assembly is separated from the transport guide assembly, and then hydraulic cylinder 2 lowers the height of the empty magazine assembly, and the engineering vehicle moves forward to make it enter the construction channel, and at the same time, the fully filled magazine assembly on pin 1 enters the docking range with the transport guide assembly, and steps 2 and 3 are performed again to achieve the operation of the next construction section.
[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, multiple magazine components are rotated to deliver the pre-processed steel bars outside the tunnel to the trolley in the tunnel, thereby reducing the labor intensity of human labor and improving the construction efficiency by relying on mechanical assistance. At the same time, the arc-shaped steel bars have a large dead weight. If they are completely attached to the bottom inner wall of the box body, the huge static friction will inevitably lead to the problem of consuming huge manpower for taking and placing the arc-shaped steel bars. Therefore, the contact surface between the two is reduced through the design of the convex ridges, thereby reducing the resistance during taking and placing, and achieving a labor-saving effect. Moreover, since the surface of the arc-shaped steel bar has annular protrusions, the lateral sliding of the arc-shaped steel bar can be avoided by mutual engagement with the convex ridges, thereby ensuring the stability of the arc-shaped steel bar during transportation and improving the safety of construction. Furthermore, the weight-reducing holes opened on the box body can reduce the dead weight, thereby reducing the wear of the bottom on the carrying guide assembly.
[0013] In the present invention, the height of the magnetic suction cup is raised by a hydraulic cylinder. When it continues to rise, the flange will continue to press down the arc pressure rod. Since the highest point of the arc pressure rod is always on the inner side of the axis center line of the core shaft, the wrench will rotate downward with the core shaft as the center until the core shaft is driven to rotate into place, so that the magnetic suction cup magnetically attracts the magnetic attraction block. At this time, the spring outside the arc guide rod is compressed under the limit of the sleeve, and the box body together with the arc steel bar will sit on the magnetic attraction block and remain stable. Then, during the process of the base being lifted, once the pin column in the transfer assembly is separated from the pin hole, the engineering vehicle can withdraw from the construction section, and the loading and transportation operations of the next box magazine assembly can be carried out outside the tunnel. Through the above-mentioned docking device, the loading of steel bars can be achieved without the need for a large amount of manpower consumption, thereby greatly improving the construction efficiency.
[0014] In the present invention, the slide moves, so that the steel bars can be transported to the front end of the guide frame. After adjusting the height by the hydraulic cylinder, the worker takes out the outermost arc-shaped steel bars and places them on the support frame, and performs the bundling operation at the same time. After completion, the slide moves to the rear end and releases and bundles the next arc-shaped steel bars in turn until the construction section is completed. In this way, the labor intensity of human beings is reduced by relying on mechanical assistance, and the situation in the existing second lining steel bar bundling construction, which is very inconvenient and labor-intensive to move and bundle the steel bars with large span and heavy weight on the top of the trolley due to the cramped space, is avoided.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example
[0018] like Figure 1-2 As shown, an embodiment of the present invention provides a tunnel construction trolley with a guide mechanism. In this embodiment, reference Figure 3 The tunnel construction trolley with a guiding mechanism includes a trolley 1, which includes a gantry 101. The trolley 1 also includes a construction passage 102 arranged in the middle of the gantry 101 for the passage of the project. Both sides of the gantry 101 are provided with multiple construction platforms 103 from top to bottom for workers to use during construction.
[0019] In this embodiment, the gantry 101 is only used as a basic structure for display. In existing mature technologies, the bottom of the gantry 101 usually also has a movable wheel set to facilitate the movement of the trolley 1.
[0020] In this embodiment, reference Figure 4-6, and also includes a carrying guide component 2, the carrying guide component 2 includes a guide frame 201 arranged on the top of the gantry 101, and the carrying guide component 2 also includes a hydraulic cylinder 202 connected to the four corners of the bottom of the guide frame 201, the bottom of the hydraulic cylinder 202 is correspondingly connected to the top of the gantry 101, and both sides of the guide frame 201 are slidably matched with guide columns 203, and the bottom of the guide column 203 is correspondingly connected to the top of the gantry 101. In this embodiment, under the guidance of the guide column 203, the height of the guide frame 201 can be stably adjusted by the hydraulic cylinder 202, and then the height of the magnetic suction cup 209 on the slide 204 can be adjusted, so as to facilitate docking with the magazine component 3 and subsequent adjustment of the bundling height of the arc-shaped steel bars 5, saving manpower.
[0021] Furthermore, a slide 204 is provided inside the guide frame 201 for sliding, and the transport guide assembly 2 also includes a hydraulic motor 205 installed at a corner of the slide 204. The driving end of the hydraulic motor 205 is connected to a gear 206. A rack 207 meshing with the gear 206 is provided on the inner side of one side of the guide frame 201. The gear 206 is driven to rotate by the hydraulic motor 205, and then with the cooperation of the rack 207, the position of the slide 204 can be accurately moved, thereby accurately placing the arc-shaped steel bars 5.
[0022] Furthermore, columns 208 are provided on both sides of one end of the slide 204, and magnetic suction cups 209 are symmetrically provided on the tops of the columns 208 on both sides. The magnetic suction cup 209 has a core shaft 2091 and a wrench 2092 connected to one end of the core shaft 2091. The middle part of the wrench 2092 is connected to an arc-shaped guide rod 210, one end of the arc-shaped guide rod 210 is sleeved with a sleeve 211 connected to the magnetic suction cup 209, the outer part of the arc-shaped guide rod 210 is sleeved with a spring 212, and one end of the wrench 2092 is connected to an arc-shaped pressure rod 213.
[0023] Note in particular that reference Figure 7-8 , wherein, when the wrench 2092 rotates downward with the core shaft 2091 as the center, the highest point of the arc-shaped pressure rod 213 is always on the inner side of the axis of the core shaft 2091.
[0024] In this embodiment, the magnetic suction cup 209 adopts the existing technology, and the wrench 2092 drives the core shaft 2091 to rotate, so as to change the magnetic field inside the magnetic suction cup 209, thereby realizing the function of magnetic attraction.
[0025] Reference again Figure 5 The transport guide assembly 2 also includes a support frame 214 installed on one side of the top of the slide 204. When the arc-shaped steel bars 5 are taken out and placed on the support frame 214, on the one hand, it is convenient for workers to stably position the height of the arc-shaped steel bars 5 during bundling, and on the other hand, it avoids the situation where the arc-shaped steel bars 5 fall out of the hands and injure the workers when the workers lose their strength.
[0026] In this embodiment, reference Figure 9-11 , and also includes at least two magazine components 3, which include an arc-shaped box body 301, and the bottom edge of the box body 301 is evenly provided with multiple axial convex ridges 302. Since the arc-shaped steel bar 5 has a large dead weight, if it is completely attached to the bottom inner wall of the box body 301, it is bound to consume a lot of manpower to take and put the arc-shaped steel bar 5 due to the huge static friction. Therefore, through the design of the convex ridges 302, the contact surface between the two is reduced, thereby reducing the resistance during taking and putting, and achieving a labor-saving effect. Moreover, since the surface of the arc-shaped steel bar 5 has an annular protrusion, the mutual engagement with the convex ridges 302 can also avoid the lateral sliding of the arc-shaped steel bar 5, thereby ensuring the stability of the arc-shaped steel bar 5 during transportation and improving the safety of construction.
[0027] Furthermore, a base 305 is installed at the bottom of the box body 301, and magnetic blocks 307 are provided on both sides of the bottom of the base 305. Slide rods 308 are connected to both sides of the top of the magnetic block 307. The slide rods 308 are matched with the inside of the base 305, and a flange 3051 is provided at the edge of the base 305.
[0028] In this embodiment, the base 305 should be made of a material that is not attracted by magnets to facilitate smooth use of the device.
[0029] Furthermore, the magazine assembly 3 also includes a weight-reducing hole 303 opened on the magazine body 301, and a limit pin 304 cooperated with both sides of the opening end of the magazine body 301. A pin hole 306 is opened in the middle of the base 305. The weight-reducing hole 303 can reduce its own weight, thereby reducing the wear of the bottom of the carrying guide assembly 2.
[0030] In this embodiment, reference Fig.12 , also includes a transfer component 4, which includes a base 401, a stand 402 installed on one side of the top of the base 401, and a hydraulic cylinder 405 installed on the other side of the top of the base 401.
[0031] Among them, a base plate 403 is installed on the top of the stand 402, a pin column 404 adapted to the pin hole 306 is installed on the top of the base plate 403, a base plate 406 is installed on the top of the hydraulic cylinder 405, a pin column 407 adapted to the pin hole 306 is installed on the top of the base plate 406, a side arm 408 is connected to one side of the base plate 406, one end of the side arm 408 is connected to a slide bar 409, the outer sliding of the slide bar 409 is matched with a slide groove 410, and the slide groove 410 is correspondingly installed on one side of the stand 402.
[0032] Furthermore, this embodiment also provides a method for using a tunnel construction trolley with a guide mechanism, comprising the following steps: Step 1: The steel bars are processed into arc shapes outside the tunnel according to the tunnel size, and then the pre-processed arc-shaped steel bars 5 are sequentially loaded into the box body 301, and the limit pin 304 is inserted to prevent the arc-shaped steel bars 5 from jumping out. The engineering vehicle transports the arc-shaped steel bars 5 to the tunnel construction section through the transfer assembly 4. Specifically, the pin hole 306 is matched with the outside of the pin column 404, and the open end of the box body 301 is faced to the trolley 1.
[0033] In this embodiment, the engineering vehicle can be a heavy-duty dump truck, a loader or a forklift. Of course, in order to ensure the smooth operation of the equipment, the base 401 needs to be adaptively designed and produced for different vehicles. In short, the base 401 needs to be designed so that the bottom plate 1 403 and the bottom plate 2 406 remain in a horizontal state. Since it only involves simple welding operations of the steel pipe structure, the adaptive design and production of the base 401 will not be repeated here.
[0034] Step 2: After entering the tunnel, keep the engineering vehicle aligned with the guide frame 201. Under the guidance of the guide column 203, lower the height of the guide frame 201 through the hydraulic cylinder 1 202, and then lower the height of the magnetic suction cup 209 on the slide 204, until the magnetic suction cup 209 is aligned and placed at the bottom of the magnetic suction blocks 307 on both sides, and then raise the height of the magnetic suction cup 209 through the hydraulic cylinder 1 202. When it continues to rise, with the cooperation of the slide bar 308, the magnetic suction cup 209 will push the magnetic suction block 307 into the inside of both sides of the base 305. At this time, the flange 3051 will continue to press down the arc pressure rod 213. The highest point is always on the inner side of the axis of the core shaft 2091, so the wrench 2092 will rotate downward with the core shaft 2091 as the center until the core shaft 2091 is driven to rotate into place, so that the magnetic suction cup 209 magnetically attracts the magnetic suction block 307. At this time, the spring 212 outside the arc guide rod 210 is compressed under the limit of the sleeve 211, and the box body 301 together with the arc steel bar 5 will sit on the magnetic suction block 307 and remain stable. Then, when the base 305 is lifted, the pin 404 in the transfer component 4 is separated from the pin hole 306, and the engineering vehicle withdraws from the construction section, and the next magazine component 3 is loaded and transported outside the tunnel.
[0035] In this embodiment, the magnetic suction cup 209 adopts the existing technology, and only adaptive modifications are performed for the use of this device, that is, the welding of the arc-shaped guide rod 210, the sleeve 211, the spring 212 and the arc-shaped pressure rod 213. Since it only involves simple welding operations of the structure, its adaptive design and production will not be repeated here.
[0036] Step 3, the slide 204 moves to the front end of the guide frame 201, and after adjusting the height by the hydraulic cylinder 202, the worker takes out the limit pin 304, and then takes out the outermost arc-shaped steel bar 5 and places it on the support frame 214, and performs the bundling operation at the same time. After completion, the slide 204 moves to the rear end and releases and bundles the next arc-shaped steel bar 5 in turn until the construction section is completed. In this way, the labor intensity of manpower is reduced by relying on mechanical assistance, and the situation of using a large amount of manual handling in the existing second lining steel bar bundling construction is avoided.
[0037] Step 4, the trolley 1 moves to the next construction section, and the engineering vehicle enters again, and step 2 is performed in reverse. When the hydraulic cylinder 1 202 is lowered, the empty magazine assembly 3 is unloaded on the pin 2 407, and the spring 212 releases the elastic force, the spindle 2091 and the wrench 2092 are reset, and the magnetic suction cup 209 releases the magnetic suction effect. The engineering vehicle retreats a certain distance, so that the empty magazine assembly 3 is separated from the carrying guide assembly 2, and then the hydraulic cylinder 2 405 lowers the height of the empty magazine assembly 3 to avoid interfering with the fully filled magazine assembly 3 at the rear. The engineering vehicle moves forward again, so that the empty magazine assembly 3 is sent into the construction channel 102, and at the same time, the fully filled magazine assembly 3 on the pin 1 404 enters the docking range with the carrying guide assembly 2, and steps 2 and 3 are performed again to achieve the operation of the next construction section.
[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

Since the highest point of the arc pressure rod (213) is always on the inner side of the axis of the core shaft (2091), the wrench (2092) will rotate downward with the core shaft (2091) as the center of the circle until the core shaft (2091) is rotated into place, so that the magnetic suction cup (209) magnetically attracts the magnetic suction block (307). At the same time, the box body (301) and the arc-shaped steel bar (5) sit on the magnetic suction block (307) and remain stable. After the transfer component (4) is separated from the pin hole (306), it is withdrawn from the construction section and the next fully filled box bin component (3) is transported; Step 3: The slide (204) moves to the front end of the guide frame (201), and after adjusting the height, the worker takes out the arc-shaped steel bars (5) and places them on the support frame (214), and performs the bundling operation at the same time. After completion, the slide (204) moves to the rear end and sequentially releases and bundles the arc-shaped steel bars (5) until the construction section is completed, thereby reducing the labor intensity of human labor by relying on mechanical assistance; Step 4: The trolley (1) moves to the next construction section, and the engineering vehicle enters again. Step 2 is performed in reverse order to unload the empty magazine assembly (3) onto the second pin (407). At the same time, the spring (212) releases its elastic force, and the magnetic suction cup (209) releases its magnetic suction effect. The engineering vehicle retreats a certain distance, so that the empty magazine assembly (3) is separated from the transport guide assembly (2). Then, the second hydraulic cylinder (405) lowers the height of the empty magazine assembly (3), and the engineering vehicle moves forward to enter the construction channel (102). At the same time, the fully filled magazine assembly (3) on the first pin (404) enters the docking range with the transport guide assembly (2). Steps 2 and 3 are performed again to achieve the operation of the next construction section.
