[0002] With the progress of the times, small prefabricated trench projects on construction sites are increasing in the construction industry. Small prefabricated trenches are also called underground pipeline common trenches, which refer to an intensive and integrated municipal public infrastructure that can accommodate two or more municipal utility pipelines, including water supply, reclaimed water, heat, electricity, telecommunications, etc. In order to facilitate the installation of pipelines in the later stage, small prefabricated trenches are set as two structures that can be assembled in the vertical direction, generally a lower trench laid on the bottom of the trench and an upper trench covered on the lower trench. The lower trench and the upper trench are generally hoisted into the dug trench, and cement is applied to the joints to seal the connection after the assembly is completed.
[0003] The hoisting of small prefabricated pipe trenches will directly affect the construction progress and economic benefits of the project. At present, there are mainly the following methods for the hoisting and installation of small prefabricated pipe trenches: manual hoisting with cranes, full manual construction, small excavators with special tools, etc.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0032] Example
[0033] See also Figure 1-4 As shown:
[0034] The utility model provides a device for assembling a small prefabricated pipe trench, comprising a horizontal suspension rod 10, a vertical rod 33, a horizontal adjustment component and a suspension device.
[0035] The top of the vertical rod 33 is connected to a lifting device that drives the vertical rod 33 to rise and fall in the vertical direction, and the bottom is vertically hinged to the middle of the horizontal suspension rod 10. In actual use, the lifting device can be an excavator, a small crane or a mobile trolley with a hand chain hoist.
[0036] In actual use, a hook 31 connected to the lifting equipment is provided at the top of the vertical rod 33, and a safety pin 32 for closing the opening of the hook 31 is provided at the opening of the hook 31. One end of the safety pin 32 abuts against the opening of the hook 31, and the other end is rotatably connected with the hook handle of the hook 31, and a torsion spring is provided at the connection between the safety pin 32 and the hook handle of the hook 31.
[0037] By such arrangement, a detachable connection is formed between the vertical rod 33 and the hoisting device, which is convenient for daily installation and storage and transportation of the device. Due to the provision of the safety pin 32, the connection between the hook 31 and the hoisting device is not easy to fall off, thereby increasing the safety of the hoisting.
[0038] The horizontal adjustment assembly is installed on the vertical rod 33, and the horizontal adjustment assembly is connected to both ends of the horizontal suspension rod 10 to adjust the horizontal angle of the horizontal suspension rod 10. The hanger is connected to the steel wire 13 arranged at both ends of the horizontal suspension rod 10, and the hanger is clamped with the lower pipe trench A or the upper pipe trench B of the prefabricated pipe trench.
[0039] The level adjustment assembly is mainly composed of a traction ring 11, a traction wire 12, an adjustment disk 21, a fixed disk 22, an adjustment handle 23 and a spirit level 40.
[0040] There are two traction rings 11 and two traction wires 12, and the two traction rings 11 are connected to the two ends of the horizontal suspension rod 10. One side of the fixed plate 22 is fixedly connected to the rod body of the vertical rod 33, and the other side is connected to the central axis of the adjustment plate 21; the adjustment handle 23 is connected to one side of the adjustment plate 21. One end of the traction wire 12 is connected to one side of the fixed plate 22, and the other end is connected to the traction ring 11. The level 40 is set in the middle of the horizontal suspension rod 10.
[0041] With such an arrangement, during actual lifting, when the lifting equipment lifts the lower pipe trench A or the upper pipe trench B to the groove where it needs to be installed, the operator observes the position of the bubble inside the spirit level 40 at close range to determine the horizontality of the lower pipe trench A or the upper pipe trench B, and then pulls the adjustment handle 23. The rotating adjustment disk 21 drives the traction wire 12 to move, thereby pulling the end of the horizontal lifting rod 10 up or down, so that the horizontality of the lower pipe trench A or the upper pipe trench B can be adjusted.
[0042] In addition, a pin is provided, and mutually aligned through holes 24 are provided on the fixed disk 22 and the adjusting disk 21; the pin and the through hole 24 form a plug-in fit.
[0043] With such an arrangement, when the operator adjusts the level of the lower pipe ditch A or the upper pipe ditch B by turning the adjustment handle 23, the pin is inserted into the through hole 24, so that the level of the horizontal suspension rod 10 does not change.
[0044] A rotation shaft is provided at the connection between the hook 31 and the vertical rod 33, so that the hook 31 and the vertical rod 33 are rotatably connected. This allows the operator to push the lower pipe ditch A or the upper pipe ditch B during the actual hoisting, so that the lower pipe ditch A or the upper pipe ditch B can be better dropped into the dug groove, or the alignment of the lower pipe ditch A and the upper pipe ditch B can be completed when the lower pipe ditch A and the upper pipe ditch B are assembled.
[0045] Since the small prefabricated pipe trough is an assembly structure consisting of an upper and lower part, in order to ensure the alignment of its assembly, a through hole a is generally provided at the edge of the lower pipe ditch A, and a tenon is provided at the edge of the upper pipe ditch B, so that the tenon and the through hole a form a mortise and tenon fit, thereby making the assembly of the lower pipe ditch A and the upper pipe ditch B more convenient and efficient. According to the structure of the lower pipe ditch A and the upper pipe ditch B, two types of lifting equipment are provided for lifting.
[0046] The first type of hanging device is provided as a hanging member 50; the hanging member 50 is engaged with the through hole a at the top edge of the lower pipe trench A.
[0047] The hanging member 50 is mainly composed of a horizontal clamping plate 51 and a horizontal short plate 52 .
[0048] A sliding groove 511 is provided on the horizontal clamping plate 51; two horizontal short plates 52 are provided in the sliding groove 511, and one end of the two horizontal short plates 52 are hinged to each other, and sliding pins 521 are provided on both sides of the other end. The two horizontal short plates 52 are both arranged in the sliding groove 511, and the sliding pins 521 form a sliding connection with the inner walls on both sides of the sliding groove 511; the steel wire 13 and the hinge of the two horizontal short plates 52 form a detachable connection.
[0049] Through such an arrangement, when the operator vertically passes the horizontal clamping plate 51 through the through hole a and then pulls the steel wire 13, the horizontal clamping plate 51 can be supported at the bottom of the through hole a, and the horizontal short plate 52 enters the through hole a as the steel wire 13 is pulled up, so that the lower pipe trench A is not easy to fall off during the lifting process, and a uniform support is formed for the edge around the through hole a, so that the edge part around the through hole a is more evenly stressed during lifting and is not easy to collapse.
[0050] The first type of hanger is configured as a clamping piece 60; the clamping piece 60 is clamped with the edge of the bottom of the upper pipe trench B.
[0051] The clamping member 60 is mainly composed of a vertical plate, a lower supporting plate 61, an upper flat plate 62, a lower flat plate 64 and a lifting ring 65. Bolt holes are provided at one end of the upper flat plate 62 and the lower flat plate 64 through which the threaded rod 63 passes; the lower supporting plate 61 is fitted and connected to the bottom of the lower flat plate 64, and is connected to the threaded rod 63 passing through the bolt hole, and the top of the threaded rod 63 is threadedly connected to the manual fastening nut 631. The top of the vertical plate is vertically connected to the upper flat plate 62, and the vertical plate is provided with a vertical guide groove 632 along the vertical direction, and the vertical guide groove 632 is slidably connected to the end of the lower flat plate 64; the steel wire 13 is detachably connected to the lifting ring 65.
[0052] The length of the upper plate 62 is shorter than that of the lower plate 64 ; the length of the lower supporting plate 61 is greater than half of the length of the lower plate 64 .
[0053] With such a configuration, in actual use, the operator clamps the upper plate 62 and the lower plate 64 on the upper and lower sides of the bottom edge of the upper pipe trench B, and then turns the manual tightening nut 631 to clamp the upper plate 62 and the lower plate 64 to the bottom edge of the upper pipe trench B. The configuration of the vertical guide groove 632 prevents the lower plate 64 from slipping during hoisting, ensuring that the area of the lower plate 64 and the upper plate 62 clamping the bottom edge of the upper pipe trench B is maximized. In addition, the configuration of the lower supporting plate 61 enables the lower plate 64 to support the bottom edge of the upper pipe trench B more stably, thereby increasing the flexibility and safety of the clamping member 60.
[0054] In addition, when the upper pipe groove B and the lower pipe groove A are assembled and aligned, only a preliminary alignment is required, and then the adjustment handle 23 is turned to lift the side of the upper pipe groove B aligned with the lower pipe groove A. The clamping member 60 on the upper pipe groove B no longer abuts against the edge of the lower pipe groove A. At this time, the operator loosens the manual fastening nut (631) of the clamping member 60, thereby easily releasing the connection between the clamping member 60 and the upper pipe groove B.
[0055] Alternatively, the tenon of the upper pipe groove B is moved to the edge of the through hole of the lower pipe groove A, and after removing the clamping member 60, the upper pipe groove B is pushed so that the tenon of the upper pipe groove B enters the through hole of the lower pipe groove A, and the assembly of the upper pipe groove B and the lower pipe groove A is completed.
