Description

Technical Field

[0001] This invention relates to the field of auxiliary technology related to tunnel operations, and in particular to a tunnel formwork lifting and conveying device. Background Technology

[0002] During tunnel construction, concrete lining is required in the tunnel walls. A tunnel trolley is used for lining, and multiple templates are installed on the trolley and on both sides. Concrete is poured between the templates and the tunnel walls. After the concrete has cured, the templates are demolded by the hydraulic cylinders of the trolley. Then the trolley moves to the next position and the work is carried out again.

[0003] The formwork on the trolley adopts a prefabricated structure. In some cases, the trolley itself is also assembled on-site. Therefore, all components, including the formwork, are transported by truck to the open space at the tunnel entrance and placed there. The formwork is usually fixed by bolts. From a single cross-section of the trolley, three formwork panels are usually assembled on its outer side. The assembly of the two formwork panels on the left and right sides is relatively simple, while the formwork panel at the top is usually lifted by workers using a crane. During the lifting process, a large number of workers are required, including the crane operator on the ground and the workers who observe from one side of the trolley via a lifting platform and manually assist in positioning the formwork. Therefore, at least two workers are required for the lifting. In addition, when the crane moves the formwork, there is a certain safety risk for the workers responsible for positioning, as they may be hit by the formwork, posing a certain safety hazard. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention provides a tunnel formwork lifting and conveying device that can save manpower required for assembling the formwork on the top of the trolley and improve safety.

[0005] In order to achieve the objectives of this invention, the following technologies are proposed:

[0006] A tunnel formwork lifting and conveying device includes:

[0007] The pusher unit includes a first rotary motor, whose output end is vertically provided with a first linear mechanism, the output end of the first linear mechanism is provided with a second linear mechanism, the output end of the second linear mechanism is provided with a crossbar, and push rods are respectively provided at both ends of the crossbar.

[0008] The positioning and flipping unit is located at one end of the push plate unit. During operation, multiple templates are stacked on the ground between the push plate unit and the positioning and flipping unit with their tops facing down. The positioning and flipping unit includes a second rotary motor. A vertically arranged third linear mechanism is fixed to one end of the outer periphery of its output shaft. A C-shaped frame is provided at the output end of the third linear mechanism. A fourth linear mechanism is provided on both sides of the C-shaped frame. A rotating cylinder is provided on one side of the output end of the fourth linear mechanism. A fifth linear mechanism is inclined above the fourth linear mechanism. An adjustment plate for contacting the arc-shaped end of the template is provided at the output end of the fifth linear mechanism.

[0009] The receiving and conveying unit is located at one end of the positioning and flipping unit. It includes a pair of receiving and conveying components located on both sides of the trolley outside the tunnel. The receiving and conveying components include a sixth linear mechanism, a seventh linear mechanism vertically provided at its output end, an eighth linear mechanism and an L-shaped plate for receiving the end of the template at the output end of the seventh linear mechanism, a third rotary motor mounted on the sliding end of the eighth linear mechanism, and a conveying plate provided at the output end of the third rotary motor.

[0010] Furthermore, the output axis of the first rotary motor is parallel to the extension direction of the track laid during tunnel construction, and the output end points to the trolley used for construction. The output axis of the second linear mechanism is parallel to the output axis of the first rotary motor, and both push rods are parallel to the second linear mechanism.

[0011] Furthermore, a rotating plate is fixed to the outer periphery of the output shaft of the second rotary motor, and a third linear mechanism is located at one end of the rotating plate.

[0012] Furthermore, the output end of the third linear mechanism is provided with a connecting block, a C-shaped frame is provided at one end of the connecting block, extension rods are provided on both sides of the connecting block, a horizontal frame and a vertical frame are provided on the side and top of one end of the extension rod, a connecting plate is also provided on one side of the upper end of the vertical frame, two fourth linear mechanisms are provided at both ends of the horizontal frame, and a fifth linear mechanism is provided at one end of the connecting plate.

[0013] Furthermore, the output axis of the fourth linear mechanism is parallel to the output axis of the second rotary motor.

[0014] Furthermore, the output end of the fourth linear mechanism is provided with a second rotating seat, one end of which is rotatably fitted with a rotating rod, and the rotating cylinder is fixed to one end of the rotating rod.

[0015] Furthermore, the sixth linear mechanism is arranged in parallel with the fourth linear mechanism.

[0016] Furthermore, the output end of the seventh linear mechanism is provided with a lifting plate, the eighth linear mechanism is located on the upper surface of the lifting plate, and an L-shaped plate is located at one end of the lifting plate.

[0017] Furthermore, the sliding end of the eighth linear mechanism is equipped with a mounting plate, and the third rotary motor is located at one end of the mounting plate.

[0018] The beneficial effects of this technical solution are as follows:

[0019] 1. By using this equipment, multiple templates can be placed directly between the push plate unit and the positioning and flipping unit on the ground. When the required template on the top of the trolley is moved, the equipment can automatically complete the movement and flipping, so that the template is in the position to be occupied by the assembly screw. No personnel are required to operate during the movement, no crane is required for hoisting, and no personnel are required to assist in moving the template from above. This can greatly reduce manpower and solve the problem of safety hazards when moving templates.

[0020] 2. There is no high accuracy requirement when the template is unloaded onto the ground. Even if the template is not stacked neatly, the position of the template can be adjusted by the positioning and flipping unit, and the whole equipment can stably and accurately deliver the template to the installation position.

Figure 2 During the construction preparation stage of tunnel 6, multiple templates 4 to be assembled on the top of the trolley 5 are lifted and transported. Specifically, the top of the trolley 5 includes multiple sets of mounting frames 51 arranged along the extension direction of the track 7. Each set of mounting frames 51 has multiple frames along the width direction of the track 7, and their top surfaces are all curved to match the inner curved surface of the template 4. Multiple reinforcing ribs 41 are also provided inside the template 4. These reinforcing ribs 41 can be locked onto one side of the mounting frame 51 to prevent the template 4 from sliding. Limiting plates 52 are also provided at the four corners of the top of the trolley 5 to limit the multiple templates 4 arranged in a straight line. After the top template 4 is assembled, the trolley 5 needs to assemble side templates located below both ends of the template 4 on both sides.

[0032] In this embodiment, the first linear mechanism 13, the second linear mechanism 14, the third linear mechanism 22, the fourth linear mechanism 25, the fifth linear mechanism 27, the sixth linear mechanism 32, and the seventh linear mechanism 33 all adopt linear hydraulic cylinders, and the eighth linear mechanism 35 adopts a linear lead screw module.

[0033] Work style:

[0034] First, such as Figure 2 As shown, multiple templates 4 that are to be mounted on the top of the trolley are stacked on the ground between the push plate unit 1 and the positioning and flipping unit 2. Usually, when transporting templates 4, they are also stacked on the truck with the top facing down as shown in the figure. Therefore, these templates 4 can be transferred directly by engineering machinery such as forklifts. At the same time, bumps will inevitably occur during transportation, so there will be a certain degree of staggered stacking between the templates 4.

[0035] The following explanation starts with template 4, which is located at the top of the stack. The remaining templates 4 are lifted and transported in the same manner.

[0036] First, the height of the second linear mechanism 14 is controlled by the first linear mechanism 13, so that the push rod 16 can only contact the uppermost template 4. Then, the push rod 16 is driven by the second linear mechanism 14 to push the template 4.

[0037] Then, the two fourth linear mechanisms 25 push the rotating cylinder 26 respectively, so that the rotating cylinder 26 provides some support to the template 4 from the side and below, and raises the template 4 a certain distance. This is mainly because when working on the template 4 at the bottom later, it needs to be raised a small distance so that the template 4 can enter the C-shaped frame 23. Then, the second linear mechanism 14 drives the push rod 16 to continue pushing the template 4 until one of its vertical surfaces touches the inner vertical surface of the C-shaped frame 23. Then, the two fifth linear mechanisms 27 control the adjusting plate 28 respectively, and the pushing stroke of the fifth linear mechanisms 27 should be the same. This is for positioning, so that the highest points at both ends of the template 4 are at the same height, and the rotating cylinder 26 is rotatable, but the adjusting plate 28 can stabilize the template 4 from above. In addition, the limiting of the C-shaped frame 23 can make the template 4 move more stably.

[0038] Next, push rod 16 is moved away from template 4. Then, the first linear mechanism 13 is rotated 180° by the first rotary motor 12. The second linear mechanism 14 is located above the first linear mechanism 13. Before or after (the order can be changed), template 4 is flipped by positioning and flipping unit 2. Specifically, template 4 is held in place. Then, template 4 is flipped upward by the second rotary motor 21. Then, the height of template 4 and push rod 16 are adjusted by the third linear mechanism 22 and the first linear mechanism 13 respectively. The height of template 4 is higher than its final installation position because it must first pass the limit plate 52.

[0039] Similarly, the L-shaped plate 39 is raised by the seventh linear mechanism 33 so that the upper end of the horizontal part of the L-shaped plate 39 is at the same height as the lowest point of the template 4, or 1cm to 3cm lower. The third rotary motor 37 first rotates the conveyor plate 38 to a vertical position. At this time, the opening of the C-shaped frame 23 faces the trolley 5. Then, the push rod 16 pushes out the template 4 by the second linear mechanism 14 so that the template 4 is completely between the two L-shaped plates 39. Then, the conveyor plate 38 is rotated to a horizontal position. The eighth linear mechanism 35 pushes the template 4 by the conveyor plate 38. For the template 4 that was originally at the top on the ground, it is obviously pushed to the end closest to the tunnel 6 first. After the pushing is completed, the template 4 is lowered by the seventh linear mechanism 33 so that the template 4 is stably placed on the mounting frame 51, thus completing the conveying of the template 4.

[0040] The sixth linear mechanism 32 can apply pressure to the template 4 by the L-shaped plate 39 during the descent of the template 4, so that the descent is more stable and less prone to slippage. It can also retract the seventh linear mechanism 33 and the components connected to its output end after all templates 4 are in place, so that the staff can complete the assembly of the components on both sides of the trolley.

[0041] The above are only some of the embodiments listed in this application and are not intended to limit this application.
