Description

Technical Field

[0001] The present invention relates to the technical field of hoisting devices, and particularly to a hoisting device for the installation of rain and sewage pipes. Background Art

[0002] Rain and sewage pipes are drainage pipes used for rainwater or sewage collection and discharge. Drainage pipes are divided into plastic drainage pipes, concrete pipes (CP), and reinforced concrete pipes (RCP).

[0003] Drainage pipes are usually arranged underground. During construction, it is necessary to excavate trenches, and then place the drainage pipes in the trenches and cover them with soil. The rain and sewage pipes installed by hoisting are large in volume and weight and are not easily moved by manpower. The width of the excavated trenches is large, so a hoisting device is used for the layout of rain and sewage pipes. The patent theme name is "A Hoisting Device for Large-Diameter Rain and Sewage Pipes", and the application number is "CN202220662988.8". The main body is a square frame, and the rain and sewage pipe is hoisted directly below the frame. In theory, the rain and sewage pipe is lowered into the trench, but it is not easy for the support legs at the lower part of the frame to span across the trench. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a hoisting device for the installation of rain and sewage pipes, including a base. One side of the upper end of the base is fixedly connected with a column, and the upper end of the column is fixedly connected with a cross beam. A hoisting mechanism is arranged on the cross beam. The upper end of the column is fixedly connected to the middle of the cross beam, so that the hoisting mechanism can move from directly above the base to one side, thereby placing the rain and sewage pipe in the trench.

[0005] The hoisting mechanism includes a moving platform. The middle of the upper end of the moving platform is fixedly connected with a first motor. The two ends of the first motor extend to be provided with rotating shafts, and winding rollers are fixedly connected to the rotating shafts. A suspension cable is wound around the winding rollers, and one end of the suspension cable is fixedly connected with a hook. The hook hooks the end of the rain and sewage pipe, and then the first motor works, and the winding roller rotates to wind the suspension cable to lift the rain and sewage pipe.

[0006] The hoisting mechanism further includes a fixed sleeve, which includes an outer sleeve. The outer sleeve is cylindrical, with a through hole in the middle. The middle part of the through hole is reduced in diameter. A cone is inserted through the middle of the through hole, and two sling ropes pass through the through hole and are clamped by the cone. When hoisting the rainwater and sewage pipe, in order to improve the stability of the hoisting of the rainwater and sewage pipe, usually the two sling ropes are arranged close to each other to prevent the hook from falling off axially from the rainwater and sewage pipe. Here, there is only the fixed sleeve. During hoisting, it is placed above the rainwater and sewage pipe close to it, so that the rainwater and sewage pipe and the two sling ropes form a triangular structure. After hoisting, the fixed sleeve receives an upward force, that is, the fixed sleeve slides upward. However, the cone is installed upside down with a larger upper part and a smaller lower part. When the fixed sleeve slides upward, the cone receives a downward force relative to the sling rope, so that the cone can clamp and fix the sling rope to prevent the fixed sleeve from sliding. It should be noted that during hoisting, the cone needs to be pressed once to make the sling rope in close contact with the inner wall of the outer sleeve and the side wall of the cone, ensuring that sufficient friction can be generated. When adjusting the position of the fixed sleeve, the cone is pushed upward in advance, and the distance between the inner wall of the outer sleeve and the side wall of the cone increases, so that the position of the fixed sleeve can be adjusted.

[0007] Preferably, a temporary storage frame is provided at the upper end of the base for placing the sewage pipe, ensuring that the device can continue to work and increasing the stability of the device at the same time.

[0008] Preferably, a battery pack is fixedly connected to the middle of the lower end of the base. Four corners of the lower end of the base are each provided with a traveling wheel, and a hub motor is provided on the traveling wheel. The battery pack is used for power supply of the device. At the same time, the battery pack is placed at the lower end of the base, reducing the center of gravity of the device and improving the stability of the device, while the traveling wheels are used to realize the movement of the device.

[0009] Preferably, rollers are provided on both sides of the moving platform, and the rollers are in rolling fit with grooves preset on the side wall of the cross beam, realizing the movement of the hoisting mechanism on the cross beam and hoisting and moving the rainwater and sewage pipe preset on the base into the groove.

[0010] Preferably, a second motor is fixedly connected to the lower end of the moving platform. The output end of the second motor is fixedly connected to a gear, and a rack is fixedly connected to the lower end of the cross beam. The gear and the rack are meshed. When the second motor is started, the gear rotates, driving the moving platform to move on the cross beam.

[0011] Preferably, a support rod is fixedly connected to the upper side wall of the column, and the other end of the support rod is fixedly connected to the lower part of the cross beam, improving the stability of the support.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The rainwater and sewage pipe can be temporarily stored on the base waiting for hoisting and installation. At the same time, the device can hoist the rainwater and sewage pipe to the trench on one side of the excavated trench, that is, hoist the rainwater and sewage pipe from the base to the trench through the hoisting mechanism.

[0014] 2. A fixed sleeve is provided. The fixed sleeve includes an outer sleeve and a cone. Its structure is simple. At the same time, during hoisting, under the action of friction, the sling can be clamped to achieve stable hoisting of the rain and sewage pipe. At the same time, by pushing up the cone, the position of the fixed sleeve can be adjusted, which has the advantage of convenient adjustment. This setting can be suitable for hoisting rain and sewage pipes of different lengths. Description of the Drawings

[0022] The present invention will be further clarified below in conjunction with the drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0023] As Figures 1 to 4 shown, the sewage pipe installation and hoisting device includes a base 2. The base 2 is a plate member. One side of the upper end of the base 2 is fixedly connected to a column 3. There are two columns 3. The upper ends of the columns 3 are fixedly connected to a cross beam 5, and the upper ends of the columns 3 are fixedly connected to the middle of the cross beam 5. One side of the cross beam 5 is directly above the base 2. A lifting mechanism 6 is provided on the cross beam 5 for hoisting and installing the rain and sewage pipe.

[0024] The lifting mechanism 6 includes a moving platform 61 which is a plate member. In the middle of the upper end of the moving platform 61, a first motor 62 is fixedly connected. The two ends of the first motor 62 are extended with rotating shafts, and winding rollers 63 are fixedly connected to the rotating shafts. When the first motor 62 is started, the rotating shafts drive the winding rollers 63 to rotate. A sling 7 is wound around the winding rollers 63. As the winding rollers 63 rotate, the sling 7 is released or wound. One end of the sling 7 is fixedly connected to a hook 9. A through hole allowing the sling to pass through is also provided on the moving platform 61. The hook 9 adopted is an acute-angled "L" shaped structure.

[0025] The lifting mechanism 6 further includes a fixed sleeve 8. The fixed sleeve 8 includes an outer sleeve 81 which is cylindrical. A through hole is provided in the middle, and the middle part of the through hole is subjected to diameter reduction treatment. As Figure 4 shown in the structure, in this perspective, the contour shape of the through hole is like a hyperbola. A cone 82 is inserted through the middle of the through hole. The cone 82 is installed in an inverted manner with the upper part larger than the lower part. At the same time, a handle is provided at the upper end of the cone 82, and a baffle is fixedly connected to the lower end of the cone 82, so that the cone 83 can be kept in the through hole, and two slings 7 pass through the through hole and are clamped by the cone 82. When lifting, it is necessary to press down the cone 82 so that the sling 7 can tightly fit against the inner wall of the outer sleeve 81 and the side wall of the cone 82. When the rain and sewage pipe is lifted, the fixed sleeve 8 obtains a vertically upward component force, which forces the fixed sleeve 8 to move upward. However, when the fixed sleeve 8 moves upward, it moves downward relative to the sling 7. Through friction, the cone 82 moves downward, reducing the distance between the inner wall of the outer sleeve 81 and the side wall of the cone 82, thereby realizing the clamping of the sling 7 by the outer sleeve 81 and the cone 82, achieving the limit of the fixed sleeve 8, and thus improving the safety of lifting.

[0026] A temporary storage frame 4 is provided at the upper end of the base 2. Above the base 2 is used for placing the rain and sewage pipe, and the temporary storage frame 4 can prevent the rain and sewage pipe from sliding off the base 2.

[0027] A battery pack 10 is fixedly connected to the middle of the lower end of the base 2. The battery pack 10 is used for the power supply of the device. At the same time, placing the battery pack 10 in a certain direction is used to change the center of gravity of the device and improve the stability of the device. Four corners of the lower end of the base 2 are all provided with traveling wheels 1, and hub motors are provided on the traveling wheels 1. When the hub motors are powered on, the device is driven to move.

[0028] Rollers 65 are provided on both sides of the moving platform 61. The rollers 65 are in rolling fit with the grooves preset on the side wall of the cross beam 5. The moving platform 61 slides on the cross beam 5 through the rollers 65.

[0029] A second motor 64 is fixedly connected to the lower end of the mobile platform 61. The output end of the second motor 64 is fixedly connected to a gear 66. A rack 67 is fixedly connected to the lower end of the cross beam 5. The gear 66 and the rack 67 are meshed. When the second motor 64 is powered on, it drives the gear 66 to rotate. With the cooperation of the rack 67, the lifting mechanism 6 is moved on the cross beam 5.

[0030] A support rod is fixedly connected to the upper side wall of the column 3. The other end of the support rod is fixedly connected to the lower part of the cross beam 5. It is used to improve the stability of the support at the upper end of the cross beam 5.
