Description

Technical Field

[0001] This utility model belongs to the field of precast concrete segment production technology, specifically relating to an anti-tipping device for transporting precast concrete segments in a workshop. Background Technology

[0002] Precast concrete segments are permanent lining structures specifically designed for use in double-shield TBM tunnel construction. Typically, a precast concrete segment production plant is integrated into any double-shield TBM tunnel project to precast the segments used for tunnel lining. The molds used in production are usually designed with the inner arc facing downwards to ensure dense concrete pouring. According to design requirements, after the finished precast concrete segments are demolded from the production line, they are transferred to a water curing tank for immersion curing. A turning platform is used to flip the precast concrete segments from a horizontal to a vertical position before they are transported to the curing area by a transport vehicle. However, due to the inertia of the transport vehicle during startup and shutdown, the risk of the precast concrete segments tipping over is particularly prominent during transportation. Therefore, to prevent the precast concrete segments from tipping over during vertical transportation, an anti-tipping device should be provided for transportation within the precast concrete segment workshop. Utility Model Content The technical problem to be solved by this utility model is to provide an anti-tipping device for transporting precast concrete segments in a workshop, which addresses the shortcomings of the prior art. The device has a simple structure and reasonable design, and can ensure that multiple precast concrete segments are always placed vertically on the flatbed of the transport vehicle, preventing them from tipping forward or backward. This reduces the safety risks of transporting multiple precast concrete segments vertically and improves the quality of the finished precast concrete segments.

[0003] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an anti-tipping device for transporting precast concrete segments in a workshop, characterized in that: it includes at least two sets of anti-tipping columns vertically arranged on the flatbed of the transport vehicle, a first clamp installed on the top of the anti-tipping columns for supporting the outermost precast concrete segment, and a second clamp arranged between two adjacent precast concrete segments. The first clamp includes a connecting plate, a connecting sleeve arranged at one end of the connecting plate for fitting onto the top of the anti-tipping column, and two limiting sleeves arranged on the bottom surface of the connecting plate. The top of the connecting sleeve has a sealing plate, and the two limiting sleeves are respectively clamped onto the inner and outer arc surfaces of the outermost precast concrete segment. The second clamp includes a support plate, a first pad, a second pad, and a third pad arranged on the bottom surface of the support plate.

[0004] The aforementioned anti-tipping device for transporting precast concrete segments within a workshop is characterized in that: the outer surfaces of the first pad and the third pad are both vertically mating planes; the first pad and the second pad each have an inwardly concave arc surface that matches the outer arc surface of the precast concrete segment; and the second pad and the third pad each have an outwardly convex arc surface that matches the inner arc surface of the precast concrete segment.

[0005] The aforementioned anti-tipping device for transporting precast concrete segments within a workshop is characterized in that: a diagonal brace is provided between the anti-tipping column and the flatbed of the transport vehicle.

[0006] The aforementioned anti-tipping device for transporting precast concrete segments within a workshop is characterized in that: two parallel long strips of square timber are arranged on the flatbed of the transport vehicle.

[0007] This utility model has the following advantages compared with the prior art: 1. This utility model involves vertically installing at least two sets of anti-tipping columns on the flatbed of a transport vehicle. Each set of anti-tipping columns includes two anti-tipping columns located on the front and rear sides of the flatbed, respectively. That is, the two sets of anti-tipping columns consist of four anti-tipping columns located at the four corners of a rectangle. By installing a first clamp on the top of the anti-tipping column, the connection between the outermost precast concrete segment and the anti-tipping column can be achieved, thus vertically supporting the outermost precast concrete segment on the flatbed of the transport vehicle. By installing a second clamp between the tops of two adjacent precast concrete segments, the precast concrete segments will not tilt forward or backward under the limiting action of the second clamp, ensuring that the precast concrete segment in the middle position is always vertically placed on the flatbed of the transport vehicle.

[0008] 2. The first clamp of this utility model includes a connecting plate, a connecting sleeve, and two limiting sleeves. The top of the connecting sleeve has a sealing plate. In actual use, the bottom of the connecting sleeve is open and the top is sealed. When the first clamp is installed on the anti-tipping column, the first clamp will not move downward along the anti-tipping column, but will always be clamped on the top of the anti-tipping column. This helps to improve the convenience and safety of the on-site installation of the first clamp. By clamping the two limiting sleeves on the inner and outer arc surfaces of the outermost precast concrete pipe segment respectively, that is, the outer circular surfaces of the two limiting sleeves are tangent to the inner and outer arc surfaces of the outermost precast concrete pipe segment respectively, the clamping connection with the outermost precast concrete pipe segment can be achieved, which is safe and reliable.

[0009] 3. The two adjacent second clamps of this utility model are connected by a vertical connecting plane, which can ensure the stability of the connection between the two second clamps; the first pad, the second pad and the third pad are all tightly fitted with the precast concrete pipe segment by the concave arc surface or the convex arc surface, which helps to improve the stability of the second clamps in the installation between two adjacent precast concrete pipe segments, and is convenient to disassemble and assemble.

[0010] 4. This utility model has a simple structure, reasonable design, low manufacturing cost, and is easy to promote and apply.

[0011] In summary, this utility model has a simple structure and reasonable design. It can ensure that multiple precast concrete segments are always placed vertically on the flatbed of the transport vehicle, preventing them from tilting forward or backward. This reduces the safety risks of transporting multiple precast concrete segments vertically and improves the quality of the finished precast concrete segments.

Detailed Implementation

[0018] like Figures 1 to 4As shown, this utility model includes at least two sets of anti-tipping columns 2 vertically arranged on the flatbed 1 of the transport vehicle, a first clamp 4 installed on the top of the anti-tipping column 2 for supporting the outermost precast concrete segment 6, and a second clamp 5 arranged between two adjacent precast concrete segments 6. The first clamp 4 includes a connecting plate 4-1, a connecting sleeve 4-2 arranged at one end of the connecting plate 4-1 for fitting onto the top of the anti-tipping column 2, and two limiting sleeves 4-3 arranged on the bottom surface of the connecting plate 4-1. The top of the connecting sleeve 4-2 has a sealing plate, and the two limiting sleeves 4-3 are respectively clamped onto the inner arc surface and the outer arc surface of the outermost precast concrete segment 6. The second clamp 5 includes a support plate 5-1, a first pad 5-2, a second pad 5-3, and a third pad 5-4 arranged on the bottom surface of the support plate 5-1.

[0019] In this embodiment, when multiple precast concrete segments 6 need to be placed vertically at intervals on the transport vehicle flatbed 1 for transportation, at least two sets of anti-tipping columns 2 are vertically installed on the transport vehicle flatbed 1. Each set of anti-tipping columns 2 includes two anti-tipping columns 2 located on the front and rear sides of the transport vehicle flatbed 1, that is, the two sets of anti-tipping columns 2 are composed of four anti-tipping columns 2 located at the four corners of a rectangle. By installing a first clamp 4 on the top of the anti-tipping column 2, the connection between the outermost precast concrete segment 6 and the anti-tipping column 2 can be realized using the first clamp 6, so that the outermost precast concrete segment 6 can be vertically supported on the transport vehicle flatbed 1. By clamping a second clamp 5 between the tops of two adjacent precast concrete segments 6, under the limiting action of the second clamp 5, the precast concrete segment 6 will not tilt to the front and rear sides, so that the precast concrete segment 6 located in the middle position can always be placed vertically on the transport vehicle flatbed 1.

[0020] In this embodiment, the first clamp 4 includes a connecting plate 4-1, a connecting sleeve 4-2, and two limiting sleeves 4-3. The top of the connecting sleeve 4-2 has a sealing plate. In actual use, the bottom of the connecting sleeve 4-2 is open and the top is sealed. When the first clamp 4 is installed on the anti-tipping column 2, the first clamp 4 will not move downward along the anti-tipping column 2, but will always be clamped on the top of the anti-tipping column 2. This helps to improve the convenience and safety of installing the first clamp 4 on site. By clamping the two limiting sleeves 4-3 onto the inner and outer arc surfaces of the outermost precast concrete pipe segment 6, respectively, that is, the outer circular surfaces of the two limiting sleeves 4-3 are tangent to the inner and outer arc surfaces of the outermost precast concrete pipe segment 6, the clamping connection with the outermost precast concrete pipe segment 6 can be achieved, which is safe and reliable.

[0021] In this embodiment, the second clamp 5 is made of hard wood or hard rubber.

[0022] like Figure 3 As shown, in this embodiment, the outer side of the first pad 5-2 and the outer side of the third pad 5-4 are both vertically mating planes 8. The first pad 5-2 and the second pad 5-3 each have an inner concave arc surface 9 that matches the outer arc surface of the precast concrete pipe segment 6. The second pad 5-3 and the third pad 5-4 each have an outer convex arc surface 10 that matches the inner arc surface of the precast concrete pipe segment 6.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, a second clamp 5 is arranged between two adjacent precast concrete segments 6. The two adjacent second clamps 5 are connected by a vertical connecting plane 8, which can ensure the stability of the connection between the two second clamps 5. The first pad 5-2, the second pad 5-3 and the third pad 5-4 are all tightly fitted with the precast concrete segments 6 through the concave arc surface 9 or the convex arc surface 10, which helps to improve the stability of the second clamp 5 in the installation between two adjacent precast concrete segments 6, and is convenient to install and remove.

[0024] In actual use, the second clamp 5 can also be decomposed into two gate-shaped clamps along the vertical center plane. That is, after hoisting a precast concrete segment 6, a gate-shaped clamp is installed on the top of the precast concrete segment 6.

[0025] In this embodiment, the heights of the limiting sleeve 4-3, the first pad 5-2, the second pad 5-3, and the third pad 5-4 are all in the range of 30cm to 60cm.

[0026] In this embodiment, a diagonal brace 3 is provided between the anti-tipping column 2 and the flatbed of the transport vehicle 1.

[0027] In this embodiment, two parallel long strips of square timber 7 are arranged on the flatbed of the transport vehicle.

[0028] like Figures 1 to 4As shown, in actual use, before hoisting the demolded precast concrete segments 6 onto the transport vehicle flatbed 1, two long strips of square timber 7 laid along the length of the transport vehicle flatbed 1 must be placed on it. It is strictly forbidden to place the precast concrete segments 6 directly onto the transport vehicle flatbed 1. Then, the placement position of the first outermost precast concrete segment 6 is determined according to the size specifications of the first clamp 4. After the first outermost precast concrete segment 6 is hoisted and placed securely, the first clamp 4 is installed on the tops of the two anti-tipping columns 2 near the first outermost precast concrete segment 6, and the two limiting sleeves 4-3 are respectively clamped onto the inner and outer arc surfaces of the outermost precast concrete segment 6. Next, multiple precast concrete segments 6 are hoisted and placed sequentially, paying attention to the hoisting and placement of the precast concrete segments... The movement of segment 6 should be slow, and collisions between precast concrete segments 6 should be strictly prohibited to prevent defects caused by collisions. After placing two precast concrete segments 6 at a time, a second clamp 5 should be placed on top of the two precast concrete segments 6. After placing the last and outermost precast concrete segment 6, the first clamp 4 should be installed on top of the two anti-tipping columns 2 near the last and outermost precast concrete segment 6, and the two limiting sleeves 4-3 should be respectively clamped on the inner and outer arc surfaces of the last and outermost precast concrete segment 6. After multiple precast concrete segments 6 are transported to the curing area, the first clamp 4 should be removed first. During the process of hoisting multiple precast concrete segments 6 in sequence, the second clamp 5 should be removed as the segments are hoisted to ensure that multiple precast concrete segments 6 are safely hoisted to the curing area.

[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
