Description

Technical Field

[0001] This utility model belongs to the field of culvert construction technology, and in particular relates to a culvert installation device. Background Technology

[0002] Culverts are an important component of urban roadbed engineering, and include pipe culverts, arch culverts, slab culverts, box culverts, etc. In the construction of pipe culverts, in order to improve the stability of the culvert construction, pipe sections are equipped with corresponding pipe supports. The pipe sections are supported by the pipe supports, and after the pipe sections are joined and assembled, they are backfilled together with the pipe supports.

[0003] Most pipe sections used in culvert construction are concrete structures and are quite heavy. To facilitate the movement of these sections on the pipe supports and enable rapid connection and assembly, culvert installation mechanisms are currently used. These mechanisms include several supports that slide on the pipe supports. The number of supports ensures that each pipe section used in culvert construction is matched with at least two supports, meaning each section is supported by at least two supports. Because the supports slide on the pipe supports, it is easy to move the pipe sections. After the pipe sections are connected and assembled, the supports do not need to be removed and can be backfilled directly along with the pipe sections and pipe supports. However, the use of culvert installation mechanisms has the following problems:

[0004] First: The large number of supports increases construction costs.

[0005] Second: The pipe section is backfilled by being supported by the support, rather than being placed on the pipe seat and directly supported by the pipe seat. This affects the stability of the pipe section support and will ultimately affect the stability of the culvert construction. Utility Model Content

[0006] In view of this, the present invention aims to provide a culvert installation device to quickly move the pipe sections used in culvert construction to the docking position, thereby improving the efficiency of culvert construction and reducing construction costs.

[0007] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0008] A culvert installation device includes a rectangular pipe seat, an arc-shaped groove corresponding to the surface of the pipe section used in the culvert construction is opened on the top surface of the pipe seat, at least two annular slots are provided on the surface of the pipe section, and a support mechanism is provided for each annular slot of the pipe seat.

[0009] The support mechanism includes a support half-ring and two sliders symmetrically arranged on the left and right sides of the arc-shaped groove and capable of sliding along the length of the pipe seat. Each slider is provided with a lifting element. The support half-ring is recessed and corresponding to the annular groove of the pipe section. The thickness of the support half-ring is not greater than the groove depth of the annular groove. The two ends of the support half-ring are detachably connected to the lifting ends of the two lifting elements. The support half-ring and the annular groove are assembled to support the pipe section.

[0010] Furthermore, the top surface of the tube seat is provided with a corresponding sliding groove for the slider, the slider and the sliding groove are assembled to form a sliding pair, and a roller is provided at the bottom of the slider, the roller abutting against the bottom of the sliding groove.

[0011] Furthermore, the groove is fitted inside the tube seat.

[0012] Furthermore, wing plates are respectively provided at both ends of the supporting semi-ring, and the wing plates have insertion holes;

[0013] The lifting end of the lifting element is provided with a support block, and the support block is provided with a pin in the corresponding insertion hole. The wing plate is supported by the support block, and the pin is inserted into the insertion hole.

[0014] Furthermore, the width of the supporting semi-ring is not greater than the groove width of the annular slot.

[0015] Furthermore, the lifting element is a pneumatic cylinder or a hydraulic cylinder.

[0016] Furthermore, the pipe seat is a concrete pipe seat.

[0017] Compared with the prior art, the culvert installation device of this utility model has the following advantages:

[0018] In this invention, the pipe sections used in culvert construction are temporarily supported by a support structure. The support mechanism is slidably mounted on the pipe seat, facilitating the movement of the pipe sections to the splicing position and improving construction efficiency. After the pipe section is moved to the splicing position, the support structure falls back, and the pipe section, along with the support semi-ring, falls back into the arc-shaped groove of the pipe seat and is supported by the pipe seat. The pipe section is then assembled on the pipe seat, and after assembly, the pipe section remains supported by the pipe seat, improving the stability of the pipe section support and ensuring the stability of the culvert construction. Meanwhile, other components of the support mechanism can be detached from the pipe section and reused, reducing the cost of culvert construction. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 , Figure 2 As shown, a culvert installation device includes a rectangular pipe base 1, which is a concrete structure. An arc-shaped groove 101, corresponding to the surface of the pipe section 2 used in the culvert construction, is longitudinally formed on the top surface of the pipe base 1 along its length. At least two annular slots 21 are provided on the surface of the pipe section 2, and a support mechanism is provided for each annular slot 21 on the pipe base 1. The support mechanism includes a supporting semi-ring 5, two sliders 3, and two lifting elements 4. Two sliders 3 are symmetrically arranged on the left and right sides of the arc-shaped groove 101, and the sliders 3 can slide along the length of the tube seat 1. Two lifting elements 4 are also symmetrically arranged on the left and right sides of the arc-shaped groove 101. The lifting elements 4 are preferably cylinders or hydraulic cylinders. The two lifting elements 4 are mounted on the two sliders 3. The supporting half-ring 5 is a concave half-ring structure with the opening facing upward. The supporting half-ring 5 and the annular groove 21 of the tube section 2 are correspondingly arranged, and the thickness of the supporting half-ring 5 itself is not greater than the groove depth of the annular groove 21, preferably less than the groove depth of the annular groove 21. The width of the supporting half-ring 5 is less than or equal to the width of the annular groove 21, preferably less than the width of the annular groove 21. The two ends of the supporting half-ring 5 are detachably connected to the lifting ends of the two lifting elements 4. The supporting half-ring 5 and the annular groove 21 are assembled and support the tube section 2. At this time, the lifting ends of the lifting elements 4 are in the extended state. The outer surface of the supporting semi-ring 5 is located in the annular groove 21. When the lifting end of the lifting element 4 retracts, the supporting semi-ring 5 and the pipe section 2 fall back to the arc groove 101. The outer surface of the pipe section 2 can be in contact with the arc groove 101, that is, the pipe section 2 can lie in the arc groove 101, so that the pipe seat 1 can stably support the pipe section 2.

[0031] In this invention, the supporting semi-ring 5 of the supporting mechanism supports the pipe section 2. The supporting mechanism can slide along the pipe seat 1, facilitating the movement of the pipe section 2. When the pipe section 2 moves, if the friction between the supporting semi-ring 5 and the outer surface of the pipe section 2 is insufficient, the pipe section 2 will move relative to the supporting semi-ring 5 until the supporting semi-ring 5 abuts against one wall of the annular groove 21. This ensures stable and synchronous movement between the supporting semi-ring 5 and the pipe section 2, i.e., the supporting mechanism and the pipe section 2 move synchronously, facilitating the movement of the pipe section 2.

[0032] Pipe section 2 structure as follows Figure 3 As shown, pipe section 2 is a concrete structure. Preferably, two annular grooves 21 are provided on the surface of pipe section 2, one at the front and one at the back. Pipe section 2 is supported by two support mechanisms at the front and back, improving the stability of pipe section 2. The pipe seat structure is as follows... Figure 5 As shown, the top surface of the tube base 1 has corresponding sliding grooves 8 on the left and right sides of the arc-shaped groove 101, respectively, for the sliders 3. The sliding grooves 8 are preferably metal and are embedded within the tube base 1. The sliders 3 and sliding grooves 8 are assembled to form a sliding pair, as shown... Figure 1 , 2 As shown, the bottom of the slider 3 is provided with a roller 9, which abuts against the bottom of the groove 8 to realize the linear movement of the pipe section 2 supported by the support mechanism.

[0033] Supporting the semi-ring 5 structure, such as Figure 4 As shown, wing plates 51 are respectively provided at both ends of the supporting semi-ring 5, and insertion holes 52 are opened on the wing plates 51. A support block 6 is provided at the lifting end of the lifting element 4, as shown... Figure 2 As shown, the support block 6 is provided with a pin 7 in the corresponding insertion hole 52. The wing plate 51 is supported by the support block 6. The pin 7 is inserted into the insertion hole 52 to realize the detachable connection between the support half ring 5 and the lifting end of the lifting element 4.

[0034] The working principle of this utility model is as follows: The lifting element 4 lifts the supporting half-ring 5 to a set height, suspending the pipe section 2 above the supporting half-ring 5 of the support mechanism. The annular groove 21 of the pipe section 2 corresponds to the position of the supporting half-ring 5. The pipe section 2 is lowered onto the supporting half-ring 5, and the supporting half-ring 5 supports the pipe section 2. The supporting half-ring 5 is embedded in the annular groove 21, forming an axial limiting structure. At this time, the pipe section 2 is directly above the arc groove 101. The pipe section 2 is pushed forward to the docking and assembly position with the previous pipe section. The lifting element 4 of the support mechanism lowers, and the pipe section 2, together with the supporting half-ring 5, lowers synchronously until it falls back into the arc groove 101 of the pipe seat 1. At this time, the pipe section 2 is supported by the arc groove 101, and the surface of the pipe section 2 is in contact with the arc groove 101. The lifting element 4 continues to lower until the pin 7 disengages from the insertion hole of the supporting half-ring 5. Figure 6 As shown, at this point, pipe section 2, along with the supporting half-ring 5, is completely detached from the lifting element 4 and can be assembled with the preceding pipe section. The support mechanism, now free of the supporting half-ring 5, can move backward, as shown... Figure 7As shown, the new supporting half-ring 5 is then reinstalled, and the above actions are repeated to complete the support and movement of each pipe section. After the pipe section assembly is completed, the supporting half-ring 5, pipe section 2, and pipe seat 1 are backfilled together.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
