Description

Technical Field

[0001] The utility model relates to the technical field of positioning brackets, in particular to a positioning bracket for water supply and drainage pipelines. Background Art

[0002] Water supply and drainage projects are used for water supply, wastewater discharge and water quality improvement. They are divided into water supply projects and drainage projects. They supply living and production water to residents and factories, mines and transportation companies. Water transportation through pipelines requires laying pipes underground. Positioning is required during the laying process to ensure the connection between pipes. However, large pipelines transport water through water level differences, and water supply and drainage pipes need to be positioned and supported during installation to ensure the stability of the drainage pipe installation. At this time, positioning brackets are needed.

[0003] The positioning bracket of the prior art cannot conveniently adjust the height of the bracket when in use, cannot adapt to the requirements of different installation heights of drainage pipes, and the existing positioning bracket cannot position and fix pipes of different diameters as required when in use, and cannot play a guiding and assisting role during pipe installation. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a water supply and drainage pipeline positioning bracket.

[0005] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: a water supply and drainage pipe positioning bracket, comprising a mounting seat, the upper surface of the mounting seat is provided with a mounting groove, the mounting groove is slidably connected with a support column, the upper surface of the support column is fixed with a fixing seat, and a clamping mechanism is arranged on the fixing seat, and the mounting seat and the support column are jointly installed with a lifting assembly for driving the support column to lift and lower, and the lifting assembly comprises a rack fixed to the lower surface of the support column, a rotating shaft that is arranged on the mounting seat and rotatably connected, a gear that is fixedly sleeved on the rotating shaft and meshed with the rack, and a rotating handle fixed to an end of the rotating shaft away from the gear. The upper surface of the fixing seat is provided with a sliding groove, and the clamping mechanism comprises a clamping piece that is slidably connected with the sliding groove, and the clamping piece is symmetrically provided with two, and two clamping wheels are rotatably connected on the side walls of the clamping piece that are close to each other, and a driving assembly for driving the two clamping pieces to move close to each other is installed on the fixing seat.

[0006] By adopting the above technical solution, the two clamping parts are driven to move closer to each other by adjusting the driving assembly, so that the two clamping parts clamp and position the water supply and drainage pipes, and the support column is slidably connected in the mounting groove of the mounting seat, and the rotating shaft and the gear are driven to rotate by rotating the handle. Since the gear is meshed with the rack, and the rack is fixed to the support column, the support column moves up and down in the mounting groove, so that the mounting seat and the clamping mechanism drive the pipes to different heights, which is convenient for installing the pipes at different heights.

[0007] Furthermore, the rotating shaft is equipped with a limiting assembly for limiting the rotating shaft, and the limiting assembly includes a ratchet fixedly sleeved on the rotating shaft, a cross bar rotatably connected to the side wall of the mounting seat, and a pawl fixedly sleeved on the cross bar and engaged with the ratchet.

[0008] By adopting the above technical solution, the pawl is engaged with the ratchet wheel, which limits the rotation of the shaft, so that the shaft and the gear can only rotate to one side, thereby preventing the support column from sliding downward, reducing the probability of the support column moving downward due to automatic rotation of the shaft.

[0009] Furthermore, a torsion spring is sleeved on the cross bar, one end of the torsion spring is fixed to the mounting seat, and the other end of the torsion spring is fixed to the side wall of the pawl.

[0010] By adopting the above technical solution, the pawl remains in a state of meshing with the ratchet wheel under the torsion force of the torsion spring, thereby reducing the probability of the pawl being out of meshing with the ratchet wheel and causing the shaft to rotate.

[0011] Furthermore, the driving assembly includes a double-headed screw that is penetrated and rotatably connected to the side wall of the fixed seat, and a rotating block fixed to the end of the double-headed screw. The double-headed screw is provided with two sections of threads with equal pitch and opposite rotation direction, and the two clamping parts are respectively threadedly connected to the two sections of the threads of the double-headed screw.

[0012] By adopting the above technical solution, when it is necessary to clamp the water supply and drainage pipes, the staff only needs to rotate the double-headed screw through the rotating block. Since the two clamping parts are respectively threadedly connected to the two sections of the double-headed screw, and the two clamping parts are slidably connected to the slide groove, the two clamping parts are moved close to each other and pressed against the water supply and drainage pipes, thereby reducing the probability of shaking of the water supply and drainage pipes and facilitating the fixing of pipes of different diameters.

[0013] Furthermore, a U-shaped seat is fixed on the upper surface of the fixed seat, and a roller is rotatably connected to the U-shaped seat.

[0014] By adopting the above technical solution, the water supply and drainage pipe is placed on the top of the roller, and when the water supply and drainage pipe is installed, the pipe is in contact with the roller, thereby providing auxiliary assistance and guidance when the water supply and drainage pipe moves.

[0015] Furthermore, a base is fixed on the lower surface of the mounting seat.

[0016] By adopting the above technical solution, the mounting seat is fixed on the ground through the base, which increases the contact area with the ground and enhances the stability of the water supply and drainage pipe positioning bracket.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. In the present application, the two clamping members are driven to move closer to each other by adjusting the driving assembly, so that the two clamping members clamp and position the water supply and drainage pipes, the support column is slidably connected in the mounting groove of the mounting seat, and the rotating shaft and the gear are driven to rotate by rotating the handle. Since the gear is meshed with the rack, and the rack is fixed to the support column, the support column moves up and down in the mounting groove, so that the mounting seat and the clamping mechanism drive the pipes to different heights, which is convenient for installing the pipes at different heights;

[0019] 2. In the present application, the pawl is meshed with the ratchet wheel, which limits the rotation of the shaft, so that the shaft and the gear can only rotate to one side, so that the support column will not slide downward, reducing the probability of the support column moving downward due to the automatic rotation of the shaft;

[0020] 3. In the present application, when it is necessary to clamp the water supply and drainage pipe, the staff only needs to rotate the double-headed screw by means of the rotating block. Since the two clamping parts are respectively threadedly connected to the two sections of the double-headed screw, and the two clamping parts are slidably connected to the slide groove, the two clamping parts are moved close to each other and pressed against the water supply and drainage pipe, thereby reducing the probability of shaking of the water supply and drainage pipe and facilitating the fixing of pipes of different diameters.

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0027] like Figure 1-4 As shown, an embodiment of the present application discloses a water supply and drainage pipe positioning bracket, including a mounting seat 1, a support column 2, a fixing seat 3, a clamping mechanism 4, a driving assembly 5 and a lifting assembly 6.

[0028] The mounting seat 1 is a structure with a rectangular cross section, and a mounting groove 11 is provided on the upper surface of the mounting seat 1. The support column 2 is a rectangular parallelepiped structure, and the support column 2 is slidably connected in the mounting groove 11. The fixing seat 3 is a rectangular parallelepiped structure, and the fixing seat 3 is fixed on the upper surface of the support column 2, and a sliding groove 31 is provided on the upper surface of the fixing seat 3.

[0029] The clamping mechanism 4 is arranged on the fixed seat 3, and the clamping mechanism 4 comprises a clamping member 41 and a clamping wheel 42. The clamping member 41 is slidably connected to the slide groove 31, and two clamping members 41 are symmetrically arranged. The clamping wheel 42 is rotatably connected to the side wall of the clamping member 41, and two clamping wheels 42 are rotatably connected to the side walls of the clamping member 41 that are close to each other.

[0030] The driving assembly 5 is mounted on the fixed seat 3 and is used to drive the two clamping members 41 to move closer to each other. The driving assembly 5 includes a double-headed screw 51 and a rotating block 52. The double-headed screw 51 is arranged on the side wall of the fixed seat 3 and is rotatably connected. The double-headed screw 51 is provided with two sections of threads with equal pitch and opposite rotation direction. The two clamping members 41 are respectively threadedly connected with the two sections of the threads of the double-headed screw 51. The rotating block 52 is a round block structure. The rotating block 52 is fixed to the end of the double-headed screw 51, and the axis of the rotating block 52 coincides with the axis of the double-headed screw 51.

[0031] The lifting assembly 6 is installed on the mounting base 1 and the support column 2, and is used to drive the support column 2 to rise and fall. The lifting assembly 6 includes a rack 61, a rotating shaft 62, a gear 63 and a rotating handle 64. The rack 61 is fixed to the lower surface of the support column 2, and the rack 61 extends vertically downward. The rotating shaft 62 is a horizontally arranged round rod-shaped structure, and the rotating shaft 62 is penetrated and rotatably connected on the mounting base 1. The gear 63 is fixedly sleeved on the rotating shaft 62, and the gear 63 is meshed with the rack 61, and the axis of the gear 63 coincides with the axis of the rotating shaft 62. The rotating handle 64 is fixed to the end of the rotating shaft 62 away from the gear 63, and the axis of the rotating handle 64 coincides with the axis of the rotating shaft 62.

[0032] When it is necessary to clamp the water supply and drainage pipe, the staff only needs to rotate the double-headed screw 51 through the rotating block 52. Since the two clamping members 41 are respectively threadedly connected to the two sections of the double-headed screw 51, and the two clamping members 41 are slidably connected to the slide groove 31, the two clamping members 41 are moved close to each other and pressed against the water supply and drainage pipe, reducing the probability of the water supply and drainage pipe shaking, which is convenient for fixing pipes of different diameters. The support column 2 is slidably connected in the mounting groove 11 of the mounting seat 1, and the rotating shaft 62 and the gear 63 are driven to rotate by rotating the handle 64. Since the gear 63 is meshed with the rack 61, and the rack 61 is fixed to the support column 2, the support column 2 moves up and down, so that the mounting seat 1 and the clamping mechanism 4 drive the pipe to be at different heights, which is convenient for installing the pipe at different heights.

[0033] In order to reduce the probability of the rotating shaft 62 rotating, the rotating shaft 62 is installed with a limiting assembly 7 for limiting the rotating shaft 62, and the limiting assembly 7 includes a ratchet 71, a cross bar 72 and a pawl 73. The ratchet 71 is fixedly sleeved on the rotating shaft 62, and the axis of the ratchet 71 coincides with the axis of the rotating shaft 62. The cross bar 72 is a horizontally arranged round rod-shaped structure, and the cross bar 72 is rotatably connected to the side wall of the mounting seat 1. The pawl 73 is fixedly sleeved on the cross bar 72, and the pawl 73 is engaged with the ratchet 71. The pawl 73 is engaged with the ratchet 71, which limits the rotation of the rotating shaft 62, so that the rotating shaft 62 and the gear 63 can only rotate to one side, so that the support column 2 will not slide downward, thereby reducing the probability of the support column 2 moving downward due to the automatic rotation of the rotating shaft 62.

[0034] In order to reduce the probability of the pawl 73 disengaging from the ratchet 71, a torsion spring 8 is sleeved on the cross bar 72, one end of the torsion spring 8 is fixed to the mounting seat 1, and the other end of the torsion spring 8 is fixed to the side wall of the pawl 73. The pawl 73 remains engaged with the ratchet 71 under the torsion force of the torsion spring 8, thereby reducing the probability of the pawl 73 disengaging from the ratchet 71 and causing the rotating shaft 62 to rotate.

[0035] In order to facilitate the movement of the water supply and drainage pipes, a U-shaped seat 9 is fixed on the upper surface of the fixed seat 3, and a roller 91 is rotatably connected to the U-shaped seat 9. By placing the water supply and drainage pipe on the top of the roller 91, and when the water supply and drainage pipe is installed, the pipe is in contact with the roller 91, thereby providing auxiliary assistance and guidance when the water supply and drainage pipe is moved.

[0036] In order to enhance the stability of the water supply and drainage pipe positioning bracket, a base 10 is fixed to the lower surface of the mounting seat 1. The mounting seat 1 is fixed to the ground through the base 10, which increases the contact area with the ground, thereby enhancing the stability of the water supply and drainage pipe positioning bracket.

[0037] The use principle of a water supply and drainage pipe positioning bracket in the present embodiment is as follows: when it is necessary to clamp the water supply and drainage pipe, the staff only needs to rotate the double-headed screw 51 through the rotating block 52. Since the two clamping members 41 are respectively threadedly connected to the two sections of the double-headed screw 51, and the two clamping members 41 are slidably connected to the slide groove 31, the two clamping members 41 are moved close to each other and pressed against the water supply and drainage pipe, reducing the probability of the water supply and drainage pipe shaking, which is convenient for fixing pipes of different diameters. The support column 2 is slidably connected in the mounting groove 11 of the mounting seat 1, and the rotating shaft 62 and the gear 63 are driven to rotate by rotating the handle 64. Since the gear 63 is meshed with the rack 61, and the rack 61 is fixed to the support column 2, the support column 2 moves up and down, so that the mounting seat 1 and the clamping mechanism 4 drive the pipe to be at different heights, which is convenient for installing the pipe at different heights.
