Description

Technical Field

[0001] This utility model relates to the field of pipeline construction, and in particular to a pipeline trench support device that facilitates excavation and laying. Background Technology

[0002] Currently, in pipeline trench excavation, it is necessary to install support devices along the length of the trench to protect its sidewalls and reduce the probability of sidewall collapse under the lateral forces of the soil. For example, Chinese patent application CN202021118799.1 discloses a pipeline trench support device that uses two protective plates and multiple horizontal steel supports. However, this existing support device has the following drawbacks:

[0003] 1. At least two horizontal steel supports should be installed near the top and bottom of both end plates. The presence of horizontal steel supports near the bottom affects the laying of pipes by construction workers in the trench, which increases the difficulty of construction and reduces construction efficiency.

[0004] 2. When excavating trenches in soft strata, it is necessary to carry out excavation and support simultaneously. That is, after excavating to a certain depth, the support device is placed into the trench, and after excavating a section, the support device is pressed down a section until the set depth is reached. The horizontal steel support near the bottom of the support device affects the excavator's bucket movement, which is not conducive to trench excavation.

[0005] Based on this, this application provides a pipeline trench support device with good support effect and convenient excavation and laying construction to solve the above problems. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art. To this end, the present invention provides a pipeline trench support device with good support effect and convenient excavation and laying construction.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A pipe trench support device that facilitates excavation and laying is provided, comprising two protective plates and a plurality of strut assemblies disposed between the two protective plates. The back of each protective plate is provided with an installation groove, and both ends of the strut assemblies are respectively fixed in the installation grooves of the two protective plates. Each strut assembly includes a horizontal strut, two diagonal struts, and a hinge seat. Both ends of the horizontal strut are respectively fixed to the installation grooves near the top of the two protective plates by pins. One end of each of the two diagonal struts is respectively fixed to the installation grooves near the bottom of the two protective plates by pins, and the other end is respectively hinged to both ends of the hinge seat by pins. The hinge seat is fixedly connected to the middle of the horizontal strut.

[0009] In some alternative embodiments, the horizontal strut consists of a central strut, connecting rods detachably mounted at both ends of the strut, and mounting seats detachably mounted at the ends of the connecting rods. The mounting seats are rotatably mounted in the mounting groove via pins.

[0010] In some alternative embodiments, the diagonal strut is a hydraulic strut, and an adjusting screw is screwed to the middle of the horizontal strut. The bottom of the adjusting screw is rotatably connected to the hinge seat, and an adjusting handwheel is fixed to its top.

[0028] Example 1

[0029] As attached Figure 1 As shown, this embodiment provides a pipeline trench support device that facilitates excavation and laying construction. It includes two protective plates 1 and multiple strut assemblies disposed between the two protective plates. Specifically, the back of each protective plate 1 has a vertical mounting groove 2, and both ends of the strut assemblies are fixed within the mounting grooves 2 of the two protective plates 1. Typically, the strut assemblies are located at both ends of the two protective plates, but one can also be installed in the middle of the two protective plates as needed.

[0030] The strut assembly in this embodiment includes a horizontal strut 3, two diagonal struts 4, and a hinge seat 5. The two ends of the horizontal strut 3 are respectively fixed to the mounting grooves 2 near the top of the two guard plates 1 by pins. One end of each of the two diagonal struts 4 is respectively fixed to the mounting grooves 2 near the bottom of the two guard plates 1 by pins, and the other end is respectively hinged to the two ends of the hinge seat 5 by pins. The hinge seat 5 is fixedly connected to the middle part of the horizontal strut 3.

[0031] Preferably, the horizontal support rod 3 in this embodiment consists of a central support rod 3.1, connecting rods 3.2 detachably mounted at both ends of the support rod, and mounting seats 3.3 detachably mounted at the ends of the connecting rods. The mounting seats 3.3 are rotatably mounted in the mounting groove 2 via pins. The horizontal support rod in this embodiment is a modular support rod, and connecting rods of different lengths can be replaced to adapt to trench support of different widths.

[0032] In this embodiment, two diagonal braces connect the guard plate and the horizontal brace, forming a stable triangular structure with the guard plate and the horizontal brace. This ensures the support effect while allowing the bottom of the guard plate to form a working channel, which not only facilitates pipeline laying but also does not affect the excavation operation of the bucket in the trench.

[0033] Example 2

[0034] Based on Example 1, as shown in the appendix Figure 2 As shown, in this embodiment, the diagonal brace 4 is configured as a hydraulic brace, and an adjusting screw 6 is screwed to the middle of the horizontal brace 3. The bottom of the adjusting screw 6 is rotatably connected to the hinge seat 5, and an adjusting handwheel 7 is fixed to its top. This design allows for adjustment of the supporting force at the bottom of the guard plate by adjusting the screw, and also allows for adjustment of the width of the bottom of the two guard plates to adapt to the support of trenches with inclined walls, thus improving the applicability of the device. In addition, this structure allows the two guard plates to be at different heights, meeting the support requirements of trenches with height differences on both sides.

[0035] Preferably, in this embodiment, the mounting base 3.3 is provided with limiting plates 3.3.1 along both sides of the mounting groove 2, and stiffening ribs are provided between the limiting plates 3.3.1 and the mounting base 3.3. Since the diagonal strut is a hydraulic strut, it is in an extended state when not supported. The setting of the limiting plates can limit the opening size of the bottom of the two guard plates, which is conducive to quickly adjusting the guard plates to a vertical state by adjusting the screw.

[0036] Preferably, in this embodiment, a spring 3.3.2 is provided between the limiting plate 3.3.1 and the bottom of the mounting groove 2, and one end of the spring 3.3.2 is fixed to the limiting plate 3.3.1. This design can provide a reverse elastic force through the spring, which can further reduce the opening size of the bottom of the two guard plates.

[0037] Preferably, the other end of the spring 3.3.2 is fixedly connected to the groove plate 3.3.3, the length of the groove plate 3.3.3 is not less than the width of the mounting groove 2, and the width of the groove plate 3.3.3 is greater than the distance between the ends of the two limiting plates 3.3.1. This design facilitates the movement of the mounting seat within the mounting groove and makes it easy to adjust the position of the mounting seat.

[0038] The mounting structure of the aforementioned diagonal brace within the mounting groove is shown in the attached figure. Figure 3 As shown: A pad 8 is provided at the end of the diagonal brace 4, and the diagonal brace 4 and the pad 8 are installed in the mounting groove 2 by means of a pin.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
