Description

Technical Field

[0001] The invention relates to the technical field of municipal road construction, in particular to a municipal road construction pipeline laying hoisting equipment. Background Art

[0002] Road pipeline laying is a common infrastructure construction in municipal construction projects. During the construction of road pipeline laying in municipal construction, the trench is first opened by machinery at the location where the pipeline needs to be laid on the municipal road. After the trench is opened, the vehicle transports the pipeline to the road on both sides of the groove, and then the pipeline is unloaded and slowly pushed into the groove. This oblique push-in method is relatively laborious, so most of them are equipped with a lifting device with a gripper. For example, in the patent CN2183202242U, a pipeline laying hoisting device is used to grab and hoist the pipeline by means of a first grab hook assembly and a second grab hook assembly. It is worth noting that the grabbing and hoisting method of the above patent content and the method of bundling and fixing with a suspension belt and then hoisting in the prior art are both time-consuming and labor-intensive, and it is difficult to grasp the balance of the hoisted pipe fittings; In addition, since the width of the groove in the area where the pipeline is placed is limited, if the diameter of the grasped pipe is large, the opening angle of the gripper will be limited, which will affect the unloading of the pipe. At the same time, it is easy to cause the pipe to move arbitrarily when it is unloaded to the laying area, greatly affecting the lifting and laying efficiency of the pipeline; In view of the technical defects in this aspect, a solution is now proposed.

DETAILED DESCRIPTION

[0016] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figure 1 - Figure 6 As shown, a municipal road construction pipeline laying hoisting equipment comprises a rectangular positioning frame 1, a half-length opening slot is arranged at the front end of the positioning frame 1, and bottom plates are fixedly installed at the front and rear ends of the positioning frame 1 and at the corners on both sides, and rollers are embedded and rotatably connected at the front and rear ends of each group of bottom plates, a loading frame 2 is fixedly installed at one end of the front end frame of the positioning frame 1 away from the opening slot, and a material guiding mechanism 3 is arranged inside the loading frame 2, and a hoisting material feeding mechanism 4 is arranged inside the positioning frame 1; The material guide mechanism 3 includes two groups of inclined material guide plates 31, which are respectively fixedly installed at the two sides of the inside of the loading frame 2. The middle section of the material guide plate 31 is arranged in a horizontal and vertical structure, and the lower end of the material guide plate 31 penetrates and extends into the inside of the positioning frame 1. Two groups of vertical plates 32 are arranged at the middle section of the inner wall of the bottom of the loading frame 2. The top of one side of the two groups of vertical plates 32 is rotatably connected with a fan-shaped lifting rod 33 through a rotating rod. The rotating rods at the two groups of fan-shaped lifting rods 33 extend to the other side of the vertical plate 32 and are fixedly installed with a transmission wheel 34. A transmission belt is sleeved between the two groups of transmission wheels 34. A motor 35 is provided between one set of transmission wheels 34 and the inner wall of one side of the loading frame 2. A vertical rod 36 is hinged at the top end of one side of the fan-shaped lifting rod 33, and a concave push frame 37 is fixedly installed at the top end of the vertical rod 36. The front and rear inner walls of the concave push frame 37 are located at the top frame opening and are symmetrically arranged with beveled surfaces.

[0018] Move the positioning frame 1 to the road construction section, and the road surface has been pre-opened with a groove for installing pipes, and it is necessary to arrange several groups of pipes in sequence in the groove; Before the pipeline is hoisted, several pipelines are arranged on the inclined surface of the higher end of the guide plate 31, and the pipelines arranged at the lowest end are blocked by the side of one group of concave push frames 37, and the motor 1 35 is started to drive one group of transmission wheels 34 to rotate, and the other group of transmission wheels 34 is driven to rotate under the action of the transmission belt; As a result, the fan-shaped lifting rod 33 connected to the two sets of transmission wheels 34 rotates accordingly, and uses the vertical rod 36 to pull the concave push frame 37 downward (sinking to the bottom of the guide plate 31), then move to one side (forcing the blocked pipe to align with it up and down), upward (forcing the pipe to be clamped into the concave push frame 37), and then move to the other side (forcing the clamped pipe to be located). The concave push frame 37 gradually realizes the progressive feeding of the pipe while making a counterclockwise circular motion. When the feeding pipe slides to the inclined surface at the other end of the guide plate 31, the pipe slides into the interior of the positioning frame 1 through the inclined surface and is received by the hoisting and feeding mechanism 4. The structure arranges the material intermittently, so that the pipe can be clamped and hoisted in order, reducing the influence of arbitrary rolling of the pipe during hoisting and hoisting efficiency.

[0019] Example 2: Please refer to Figure 2 , Figure 4 - Figure 6 As shown, the hoisting and feeding mechanism 4 includes a second motor 41, which is arranged at the rear end of the inner wall of one side of the positioning frame 1, and a threaded rotating rod 42 is fixedly installed at the output end of the second motor 41, and the two ends of the threaded rotating rod 42 are respectively movably connected with a movable plate 43 and a fixed plate 44, and the rear ends of the movable plate 43 and the fixed plate 44 are extended to the transverse groove provided on the inner wall of the rear end of the positioning frame 1, and the fixed plate 44 is fixedly connected to the inner wall of the slide groove; The threaded rotating rod 1 42 is threadedly connected to the inner hole groove of the movable plate 43, and the end of the threaded rotating rod 1 42 is rotatably connected to the fixed plate 44. A guide rod 45 is connected between the movable plate 43 and the fixed plate 44, and the end of the guide rod 45 is fixedly connected to the inner wall of the positioning frame 1. Two groups of wedge-shaped abutting rods 46 are fixedly installed at the front end of the guide rod 45 close to the end of the fixed plate 44. A concave material receiving frame 47 is provided at one side of the movable plate 43 and at the front end, and a threaded rotating rod 2 48 is fixedly installed at the front end of the fixed plate 44 and at the side opposite to the movable plate 43; A clamping frame 49 is provided at the upper and lower ends of the material receiving frame 47. A V-shaped groove is provided at the center of the opposite surfaces of the two sets of clamping frames 49, and a sliding shaft 410 is fixedly installed at the center of the rear end surface of the clamping frame 49. The two sets of sliding shafts 410 are respectively slidably connected in the vertical grooves opened at the upper and lower ends of the rear end of the clamping frame 49. A motor 3 411 is provided at the center of the rear end of the clamping frame 49, and a rotating plate 412 is fixedly installed at the output shaft of the rear end of the motor 3 411. The upper and lower ends of the rotating plate 412 are respectively provided with inner grooves, and the rear end rod body of the sliding shaft 410 slides in the inner groove; The pipes after intermittent feeding are sequentially slid into the receiving frame 47 and clamped in the V-shaped groove of the bottom clamping frame 49. The motor 3 411 is started to drive the rotating plate 412 to rotate counterclockwise, and the upper and lower ends of the rotating plate 412 press against the corresponding sliding shafts 410 respectively. The two sets of sliding shafts 410 slide along the inside of the vertical groove and along the inside of the inner groove at the same time. Thus, the upper and lower sets of sliding shafts 410 and the clamping frame 49 are close to each other, and the upper and lower sets of clamping frames 49 clamp the pipe fittings together. At the same time, a threaded rotating cylinder 413 is fixedly installed at the center of one side of the material receiving frame 47 away from the movable plate 43, and the inside of the threaded rotating cylinder 413 is adapted to the threaded rotating rod 48. After the pipe is clamped, the motor 41 is started to drive the threaded rotating rod 42 to rotate, and the threaded rotating rod 42 rotates in coordination with the thread groove inside the movable plate 43, and drives the movable plate 43 and the material receiving frame 47 to move linearly; When the material receiving frame 47 moves to the position corresponding to the notch at the front end of the positioning frame 1, the threaded rotating cylinder 413 approaches the threaded rotating rod 2 48, and the threaded rotating rod 2 48 is inserted into the threaded rotating cylinder 413, forcing the threaded rotating cylinder 413 and the material receiving frame 47 to turn counterclockwise by 90 degrees. At this time, the clamped pipe fitting corresponds to the installation position up and down, and then the motor 3 411 drives the rotating plate 412 to rotate clockwise, forcing the two sets of clamping frames 49 to reset and lose the clamping of the pipe, so that the pipe is vertically discharged to the laying area; It is worth noting that the pipeline of the drainage system is formed by connecting multiple groups of branch pipelines in sequence. Therefore, during the subsequent lifting and feeding, the unloading position of the pipeline will be constantly changed, and the pipeline laying position can be changed by moving the positioning frame 1; The inner wall at the bottom of the material receiving frame 47 is located at the bottom of the clamping frame 49 and a limit assembly 5 is provided. The limit assembly 5 includes two groups of clamping rods 51, which are respectively arranged on the inner wall at the bottom of the material receiving frame 47 and located at both sides of the clamping frame 49, and the middle section of the clamping rod 51 and the upper and lower ends of the bottom frame of the material receiving frame 47 are fixedly installed with clamping plates, and the outside of the clamping rod 51 and located between the bottom surface of the material receiving frame 47 and the bottom clamping plate are jointly wound with a spring group coil 52, the top ends of the opposite surfaces of the two groups of clamping rods 51 are arranged in an oblique section, and the rear end surface of the clamping rod 51 is located at the bottom rod body and is also arranged in an oblique section; As the pipe flips along with the material receiving frame 47, the limit assembly 5 also flips accordingly. The bottom chamfered surfaces of the two groups of clamping rods 51 are flipped and respectively abut against the two groups of wedge-shaped abutting rods 46. As a result, the other ends of the two groups of clamping frames 49 move toward the two ends of the pipe inside the material receiving frame 47, and use the chamfered surfaces to contact the two ends of the pipe respectively to assist in centering the pipe. At the same time, when the pipe is cut to the installation position, the two groups of clamping rods 51 are respectively limited at the two ends of the pipe to reduce the deviation of the pipe when it is cut, thereby further improving the efficiency of pipe installation.

[0020] This structure can not only realize automatic clamping of the pipeline and stable transportation and unloading, but also align and limit the end of the pipeline when it is unloaded to the laying position, so as to reduce pipeline deviation and further improve the efficiency of pipeline hoisting and laying.

[0021] Working principle: When the present invention is used, firstly, the positioning frame 1 is moved to the road construction section, and the road surface has been pre-opened with a groove for installing pipes, and then several groups of pipes need to be arranged in sequence in the groove; Before the pipeline is hoisted, several pipelines are arranged at the inclined surface of the higher end of the guide plate 31, and the pipelines arranged at the lowest end are blocked by the side of one group of concave push frames 37. The motor 35 is started to drive one group of transmission wheels 34 to rotate, and the other group of transmission wheels 34 is driven to rotate under the action of the transmission belt, thereby, the fan-shaped lifting rod 33 connected to the two groups of transmission wheels 34 rotates accordingly, and the vertical rod 36 is used to pull the concave push frame 37 downward (sinking to the bottom of the guide plate 31), then move to one side (forcing the blocked pipeline to align with it up and down), upward (forcing the pipeline to be clamped into the concave push frame 37), and then move to the other side (forcing the clamped pipeline to be located), the concave push frame 37 gradually realizes the progressive feeding of the pipeline while making counterclockwise circular motion, and when the feeding pipeline slides to the inclined surface at the other end of the guide plate 31, the pipeline slides into the interior of the positioning frame 1 through the inclined surface and is received by the hoisting and feeding mechanism 4; The pipes are sequentially slid into the inside of the receiving frame 47 and clamped in the V-shaped groove of the bottom clamping frame 49. The motor 3 411 is started to drive the rotating plate 412 to rotate counterclockwise, and the upper and lower ends of the rotating plate 412 press against the corresponding sliding shafts 410 respectively. The two sets of sliding shafts 410 slide along the inside of the vertical groove and along the inside of the inner groove at the same time. As a result, the upper and lower sets of sliding shafts 410 and the clamping frame 49 are close to each other, and the upper and lower sets of clamping frames 49 clamp the pipe fittings together. After the pipe is clamped, start motor 2 41 to drive threaded rotating rod 1 42 to rotate. Threaded rotating rod 1 42 rotates in coordination with the internal thread groove of movable plate 43, and drives movable plate 43 and material receiving frame 47 to move in a straight line, until material receiving frame 47 moves to the corresponding position of the notch at the front end of positioning frame 1, threaded rotating cylinder 413 approaches threaded rotating rod 2 48, and threaded rotating rod 2 48 is inserted into threaded rotating cylinder 413, forcing threaded rotating cylinder 413 and material receiving frame 47 to turn counterclockwise by 90 degrees. At this time, the clamped pipe fitting corresponds to the installation position up and down, and then motor 3 411 is used to drive rotating plate 412 to rotate clockwise, forcing the two sets of clamping frames 49 to reset and lose the clamping of the pipe, and the pipe is then vertically discharged to the laying area.
