Description

Technical Field

[0001] This utility model belongs to the field of municipal construction technology, specifically relating to an auxiliary device for the construction of municipal public utility pipe wells. Background Technology

[0002] Municipal utility manhole construction auxiliary devices are auxiliary facilities used in the construction of municipal pipelines to ensure the safety, efficiency, and smooth progress of the construction. Common auxiliary devices include manhole support frames, manhole wall reinforcement facilities, dewatering equipment, and lighting facilities. Support frames and manhole wall reinforcement facilities are used to prevent manhole wall collapse and ensure the safety of construction personnel.

[0003] Chinese patent publication number CN218263554U discloses a municipal utility manhole construction auxiliary device, including a base. A movable device is fixedly connected to both the left and right ends of the base. A first-order fixing bolt is threadedly connected to the middle of the left and right ends of each movable device. An adjustment device is movably connected to the upper ends of four limiting rods. A fixing plate is fixedly connected to the middle of the front and right walls of the base. A limiting cylinder is fixedly connected to the middle of the upper end of the fixing plate. Several first-order screw holes are opened on the front surface of the limiting cylinder, and a second-order fixing bolt is threadedly connected to the front surface of the limiting cylinder. This municipal utility manhole construction auxiliary device, by incorporating adjustment and movable devices throughout the device, provides warning signals from all sides, enhancing the construction warning effect and facilitating the movement of the entire device, thus effectively meeting user needs.

[0004] However, the current construction auxiliary device has the following problems: when the main body of the manhole is installed, the bottom surface of the installation hole is uneven, which causes the angle and position of the manhole body to shift after installation. The shift leads to uneven support of the manhole, resulting in local stress imbalance. Under long-term use, this can cause the manhole to deform or even collapse, affecting the safety of municipal facilities. Therefore, we propose a construction auxiliary device for municipal public manholes. Utility Model Content

[0005] The purpose of this utility model is to provide a construction auxiliary device for municipal utility manholes, which can solve the problem in related technologies where the bottom surface of the installation hole is uneven during the installation of the manhole body. This unevenness causes the angle and position of the manhole body to shift after installation, resulting in uneven support of the manhole, causing local stress imbalance, and leading to deformation or even collapse of the manhole under long-term use, thus affecting the safety of municipal facilities.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A municipal utility manhole construction auxiliary device includes a base. Four electric push rods are fixedly connected to the top of the base. A fixed frame is fixedly connected to the telescopic ends of the four electric push rods. An inward-retracting device is provided on the top of the fixed frame. The inward-retracting device includes a gantry frame. The bottom of the gantry frame is slidably connected to the top of the fixed frame. A disc is fixedly connected to the bottom of the gantry frame. A torsion block is fixedly connected to the top of the disc. Two connecting rods are fixedly connected to the bottom of the disc. A driving assembly is provided on the facing surfaces of the connecting rods. A slotted disc is fixedly connected to the bottom of each of the two connecting rods. A long rod is slidably connected to the inner wall of the slot of the slotted disc. An inward-retracting plate is fixedly connected to the bottom of the long rod, and a round rod is fixedly connected to the top of the long rod.

[0008] The drive assembly includes a U-shaped frame, with both ends of the U-shaped frame fixedly connected to the sides of the connecting rod. A motor is fixedly connected to the top of the U-shaped frame, and a rotating shaft is fixedly connected to the output shaft of the motor. An arc-grooved disc is fixedly connected to the circumferential surface of the rotating shaft, and the rotating shaft is the rotating end of the drive assembly.

[0009] The base is equipped with four casters at its bottom, and the round rod is in contact with the inner wall of the arc-shaped groove of the arc-shaped groove plate.

[0010] An expansion device is provided on the side of the rotating shaft. The expansion device includes four arc-shaped discs, the bottom of which is fixedly connected to the bottom of the rotating shaft. Sliding rods are slidably connected to the inner walls of the four arc-shaped discs. A central shaft is fixedly connected to the bottom of the slotted disc. A hollow cylinder is fixedly connected to the circumference of the central shaft. Four sliding rods pass through and slide on the circumference of the hollow cylinder. An expansion plate is fixedly connected to the end of each of the four sliding rods away from the central shaft.

[0011] There is a gap between the expansion plate and the inner plate, and the slide rod is located on the movement trajectory of the slide column.

[0012] The end of the expansion plate away from the slide bar has an arc design, and the expansion plate is made of a high-toughness, non-slip material.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model, through the setting of the inward-retracting device, enables the gantry frame, disc, torsion block, connecting rod, slotted disc, long rod, inward-retracting plate, round rod, arc-shaped slotted disc, U-shaped frame, motor, and rotating shaft to cooperate. When the motor is started, the output shaft of the motor rotates, which in turn drives the rotating shaft to rotate. The rotation of the arc-shaped slotted disc causes the round rod to move along the inner wall of the arc-shaped slotted disc. The movement of the round rod causes the long rod to move within the slotted disc. The movement of the long rod causes the inward-retracting plate to move inward. The inward movement of the inward-retracting plate can limit the lateral position of the manhole, thereby avoiding unevenness at the bottom of the mounting hole during the installation of the manhole body. This would prevent the manhole body from shifting in angle and position after installation due to unevenness. Such shifting would lead to uneven support of the manhole, causing localized stress imbalance. Over long-term use, this could cause the manhole to deform or even collapse, affecting the safety of municipal facilities.

[0015] This utility model, through the setting of the expansion device, enables the four-arc disc, sliding column, central shaft, hollow cylinder, sliding rod, and expansion plate to cooperate. At the same time, the rotation of the rotating shaft drives the rotation of the four-arc disc, and the rotation of the four-arc plate drives the movement of the sliding column. During the movement, the sliding column will abut against the sliding rod, causing the sliding rod to move outward. The outward movement of the sliding rod drives the expansion plate to move outward. The outward movement of the expansion plate can increase the clamping force and prevent the well pipe from falling off due to insufficient clamping force during installation.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1 - Figure 5 As shown, a municipal utility manhole construction auxiliary device includes a base 1. Four electric push rods 2 are fixedly connected to the top of the base 1. A fixed frame 3 is fixedly connected to the telescopic ends of the four electric push rods 2. An inward retraction device 4 is provided on the top of the fixed frame 3. The inward retraction device 4 includes a gantry frame 41. The bottom of the gantry frame 41 is slidably connected to the top of the fixed frame 3. A disc 42 is fixedly connected to the bottom of the gantry frame 41. A torsion block 43 is fixedly connected to the top of the disc 42. Two connecting rods 44 are fixedly connected to the bottom of the disc 42. A driving assembly is provided on the facing surfaces of the connecting rods 44. A slotted disc is fixedly connected to the bottom of each of the two connecting rods 44. 45. A long rod 46 is slidably connected to the inner wall of the groove of the slotted disc 45. An inner plate 47 is fixedly connected to the bottom of the long rod 46. A round rod 48 is fixedly connected to the top of the long rod 46. The drive assembly includes a U-shaped frame 410. The two ends of the U-shaped frame 410 are fixedly connected to the sides of the connecting rod 44. A motor 411 is fixedly connected to the top of the U-shaped frame 410. A rotating shaft 412 is fixedly connected to the output shaft of the motor 411. An arc-shaped slotted disc 49 is fixedly connected to the circumferential surface of the rotating shaft 412. The rotating shaft 412 is the rotating end of the drive assembly. Four universal wheels 6 are provided at the bottom of the base 1. The round rod 48 is in contact with the inner wall of the arc-shaped groove of the arc-shaped slotted disc 49.

[0025] Based on the above structure, the manhole is placed at the center of the base 1. The operator twists the torsion block 43, which in turn rotates the disc 42. The disc 42 then rotates the connecting rod 44, causing the slotted disc 45 to rotate. The slotted disc 45 then rotates the long rod 46. The motor 411 is then started. The output shaft of the motor 411 rotates, causing the rotating shaft 412 to rotate. The rotating shaft 412 then rotates the arc-shaped slotted disc 49, causing the round rod 48 to move along the arc-shaped slotted disc 49. The inner wall of 9 moves, and the movement of the round rod 48 drives the long rod 46 to move within the slotted disc 45. The movement of the long rod 46 drives the inner retracting plate 47 to move inward. The inward movement of the inner retracting plate 47 can limit the lateral position of the manhole, thereby avoiding unevenness at the bottom of the installation hole during the installation of the manhole body. This would prevent the manhole body from shifting in angle and position after installation. Such shifting would cause uneven support of the manhole, resulting in local unbalanced force. Over long-term use, this could lead to deformation or even collapse of the manhole, affecting the safety of municipal facilities.

[0026] like Figure 1 - Figure 5 As shown, an expansion device 5 is provided on the side of the rotating shaft 412. The expansion device 5 includes a four-arc disc 51. The bottom of the four-arc disc 51 is fixedly connected to the bottom of the rotating shaft 412. A sliding column 52 is slidably connected to the inner wall of the four-arc disc 51. A central shaft 53 is fixedly connected to the bottom of the slotted disc 45. A hollow cylinder 54 is fixedly connected to the circumference of the central shaft 53. Four sliding rods 55 pass through and slide on the circumference of the hollow cylinder 54. An expansion plate 56 is fixedly connected to the end of the four sliding rods 55 away from the central shaft 53. There is a gap between the expansion plate 56 and the inner plate 47. The sliding rods 55 are located on the movement trajectory of the sliding column 52. The end of the expansion plate 56 away from the sliding rods 55 is designed with an arc surface. The expansion plate 56 is made of a high-toughness anti-slip material.

[0027] According to the above structure, the rotation of the rotating shaft 412 drives the rotation of the four-arc disc 51, and the rotation of the four-arc disc 51 drives the movement of the sliding column 52. During the movement, the sliding column 52 will abut against the sliding rod 55, causing the sliding rod 55 to move outward. The outward movement of the sliding rod 55 drives the expansion plate 56 to move outward. The outward movement of the expansion plate 56 can increase the clamping force and prevent the well from falling off due to insufficient clamping force during installation.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
