Installation equipment for socket-type reinforced concrete pipe

Abstract

This invention conforms to the field of concrete pipe installation technology, mainly pointing out an installation device for socket-type reinforced concrete pipes. It addresses the limitation of existing U-shaped lifting devices that cannot adaptively adjust their length according to the pipe length. The device includes: a U-shaped frame; a support rod slidably connected to the U-shaped frame; a drive motor mounted on the U-shaped frame, the output shaft of which is fixedly connected to a threaded rod, which is rotatably connected to the U-shaped frame; a plug block slidably connected to the support rod and engaging with the threaded rod; a lifting ring disposed on the U-shaped frame; and an intercepting mechanism disposed on the support rod for blocking the pipe. This invention increases the length of the U-shaped frame by moving the support rod, thereby increasing the contact area between the U-shaped frame and the pipe, ensuring complete contact between the inner wall of the pipe and the U-shaped frame. This prevents the pipe from tilting during lifting, thus avoiding uneven stress that could lead to cracks or even breakage.

Description

Technical Field

[0001] The invention belongs to the technical field of concrete pipe installation, and specifically discloses an installation device for a socket-and-spigot type reinforced concrete pipe. Background Art

[0002] Socket-and-spigot concrete pipes are a common type of pipe used in drainage, sewage and other fields. The core feature of this type of pipe is their unique connection method: the socket connection. Specifically, this method involves inserting one end of one pipe (the spigot, which is the small end of the pipe and is located downstream) into one end of another pipe (the socket, which is the large end of the pipe and is located upstream), and using sealing materials such as rubber rings to ensure the tightness and waterproof performance of the interface.

[0003] When installing the socket-and-spigot concrete pipe, a lifting device is used to lift it and move it to a specified position. The existing lifting method is to use a crane to tie the concrete pipe to the crane through a strap for lifting, or to use a horizontal U-shaped lifting device to lift the pipe. However, the size of the U-shaped lifting device is generally fixed. When lifting a concrete pipe that is longer than the U-shaped lifting device, the U-shaped lifting device cannot completely contact the concrete pipe. After the concrete pipe is lifted, the instability of the center of gravity of the concrete pipe causes the concrete pipe to tilt longitudinally, resulting in uneven force on the concrete pipe and local stress concentration, which can cause the concrete pipe to break. If the concrete pipe is too long, it may even cause the concrete pipe to slip. Summary of the invention

DETAILED DESCRIPTION

[0062] The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0063] After research, it was found that in the process of installing the socket-type reinforced concrete pipe, a transverse U-shaped hanger is used. The U-shaped hanger is inserted into the concrete pipe horizontally and lifted by the lifting equipment to realize the lifting of the concrete pipe; however, when the length of the U-shaped hanger is greater than the length of the U-shaped hanger during use, the concrete pipe will be tilted during the lifting process because it is not completely in contact with the U-shaped hanger. The tilting causes one end of the concrete pipe to be subjected to greater pressure, which will cause the material in this area to be subjected to pressure exceeding its designed bearing capacity, causing stress concentration. Uneven force and stress concentration may cause tiny cracks in some weak points of the concrete pipe, affecting the use of the concrete pipe in the later stage. To solve this problem, this paper proposes the following solutions, as follows;

[0064] A device for installing socket-type reinforced concrete pipes, Figure 1-Figure 5As shown, it includes: a U-shaped frame 1; a support rod 2, which is slidably connected to the U-shaped frame 1; a driving motor 3, which is installed on the U-shaped frame 1, and the output shaft of the driving motor 3 is fixedly connected to a threaded rod 4, and the threaded rod 4 is rotatably connected to the U-shaped frame 1; a plug-in block 5, which is slidably connected to the support rod 2 and is squeezed and matched with the threaded rod 4; a lifting ring 6, which is arranged on the U-shaped frame 1; an intercepting mechanism, which is arranged on the support rod 2 and is used to block the pipeline.

[0065] In this embodiment, the connection between the lifting ring 6 and the U-shaped frame 1 is fixed, and the position of the lifting ring 6 is not adjusted.

[0066] It is worth mentioning that: the U-shaped frame 1 is an existing U-shaped hanger, and a rubber pad is arranged on the inner side of the U-shaped frame 1 (in contact with the pipeline) to buffer the tension applied to the pipeline and prevent the pipeline from being subjected to excessive concentration of force; a rubber pad is also arranged on the upper side of the support rod 2, and the upper side of the support rod 2 is flush with the inner side of the U-shaped frame 1 to ensure simultaneous contact with the pipeline, thereby preventing the support rod 2 and the U-shaped frame 1 from contacting the pipeline at uneven positions, thereby causing uneven force on the pipeline and damaging the inner wall of the pipeline; a convex ball is arranged on the inner side of the plug-in block 5, and the plug-in block 5 is squeezed and matched with the threaded rod 4 through its own convex ball, that is, when the threaded rod 4 rotates, the thread on the threaded rod 4 squeezes the convex ball of the plug-in block 5 to move the plug-in block 5.

[0067] The process of the above scheme is as follows: when using the device to hoist the pipeline, first connect the lifting ring 6 to the hook of the crane, then control the crane to lower the U-shaped frame 1 to the vicinity of the pipeline, and the user pushes the U-shaped frame 1 and inserts it into the pipeline. At this time, if the length of the pipeline is less than the length of the U-shaped frame 1, the pipeline can be directly lifted by the crane and moved to the designated position.

[0068] If the length of the pipeline is greater than the length of the U-shaped frame 1, the user turns on the drive motor 3, and the output shaft of the drive motor 3 drives the threaded rod 4 to rotate. The threaded rod 4 moves by squeezing the plug-in block 5 thereon, and the plug-in block 5 drives the support rod 2 to move synchronously. The support rod 2 gradually extends until the end of the support rod 2 extends out of the pipeline. The user turns off the drive motor 3. In this way, the length of the U-shaped frame 1 is increased by moving the support rod 2, and then the contact area between the U-shaped frame 1 and the pipeline is increased, ensuring that the inner wall of the pipeline is completely in contact with the U-shaped frame 1, thereby preventing the pipeline from tilting during the lifting process, and thus avoiding uneven force on the pipeline causing cracks or even breakage.

[0069] When the support rod 2 extends outward, the support rod 2 drives the interception mechanism to move synchronously. When the support rod 2 stops moving, the interception mechanism starts to work and limits the pipeline to prevent it from sliding out of the U-shaped frame 1.

[0070] In particular, the control Figure 4 , Figure 6 and Figure 7 As shown, the interception mechanism includes: an interception rod 21, which is slidably connected to the support rod 2; a first elastic member 22, which is arranged between the interception rod 21 and the support rod 2; a positioning assembly, which is arranged on the side of the support rod 2 close to the interception rod 21, and is used to control the movement of the interception rod 21; and a locking assembly, which is arranged on the support rod 2 and is used to limit the support rod 2.

[0071] It is worth mentioning that: the above scheme proposes a method of limiting the pipeline; the upper side of the intercepting rod 21 is rotatably connected with a rotating wheel to reduce the wear on the pipeline, and the upper side of the rotating wheel on the intercepting rod 21 is flush with the support rod 2; the first elastic member 22 is a spring, which is used to drive the intercepting rod 21 to move, and the first elastic member 22 is initially in a compressed state.

[0072] The process of the above scheme is as follows: when the U-shaped frame 1 is inserted into the pipeline, the pipeline squeezes the positioning assembly so that the positioning assembly releases the limit on the intercepting rod 21. Since the upper side of the intercepting rod 21 is always flush with the inner side of the support rod 2, the intercepting rod 21 will not move upward.

[0073] When the support rod 2 extends outward, the support rod 2 drives the intercepting rod 21 to move, and the rotating wheel of the intercepting rod 21 contacts the inner wall of the pipe, while the first elastic member 22 does not extend.

[0074] During the movement of the intercepting rod 21, when the intercepting rod 21 moves out of the pipeline, one end of the support rod 2 also protrudes out of the pipeline, and the driving motor 3 is turned off. Thereafter, the intercepting rod 21 moves upward under the elastic action of the first elastic member 22, so that its upper side is higher than the pipeline and fits against the side wall of the pipeline, thereby blocking one end of the pipeline. The intercepting rod 21 and the U-shaped frame 1 are used to fix both sides of the pipeline to prevent the pipeline from slipping during the lifting process and causing damage to the pipeline.

[0075] During the upward movement of the intercepting rod 21, the intercepting rod 21 drives the plug-in block 5 to move through the locking assembly and separates it from the threaded rod 4, while locking the support rod 2 to prevent the support rod 2 from sliding during the lifting process and affecting the stability of the pipeline.

[0076] In particular: Figure 6 and Figure 7 As shown, the locking assembly includes: a sliding rod 31, which is slidably connected to the support rod 2; a second elastic member 32, which is arranged between the sliding rod 31 and the support rod 2; a limiting rod 33, which is slidably connected to the support rod 2 and is squeezed and matched with the sliding rod 31, and the limiting rod 33 is limitedly matched with the intercepting rod 21.

[0077] It is worth mentioning that: the above scheme proposes a method of limiting the intercepting rod 21; the upper side of the sliding rod 31 is higher than the upper side of the intercepting rod 21, and a rubber pad is provided on the upper side of the sliding rod 31 to reduce damage to the pipeline, and an inclined slide groove is provided on the lower side of the sliding rod 31; the second elastic member 32 is a spring to drive the sliding rod 31 to move upward and reset; the sliding rod 31 is squeezed and matched with the limiting rod 33 through the inclined slide groove thereon, and when the inclined slide groove moves up and down, the limiting rod 33 is pressed to move forward and backward.

[0078] The process of the above scheme is as follows: when the U-shaped frame 1 is inserted into the pipeline, the pipeline squeezes the sliding rod 31, the sliding rod 31 moves downward, and compresses the second elastic member 32. The sliding rod 31 squeezes the limiting rod 33 through the inclined slide groove thereon. The limiting rod 33 is pressed and moves backward and releases the limiting of the intercepting rod 21. At this time, the intercepting rod 21 contacts the inner wall of the pipeline and does not move upward.

[0079] When the pipe loses contact with the sliding rod 31 (ie the intercepting rod 21 extends upward), the sliding rod 31 moves upward under the elastic action of the second elastic member 32 , thereby resetting the limiting rod 33 .

[0080] In particular: Figure 3 and Figure 6-Figure 9 As shown, the locking assembly includes: a sliding plate 41, which is slidably connected to the support rod 2, and the sliding plate 41 is provided with a first groove 4101 and a second groove 4102, the intercepting rod 21 is extruded and matched with the first groove 4101, and the plug-in block 5 is extruded and matched with the second groove 4102; a limiting rack 42, which is fixed to the U-shaped frame 1 and is limited and matched with the plug-in block 5; the first groove 4101 is composed of a vertical portion, an inclined portion and a horizontal portion, and the three are arranged in sequence from top to bottom, the second groove 4102 is provided with two horizontal portions and an inclined portion, and the inclined portion is located between the two horizontal portions; the plug-in block 5 is provided with a limiting portion, and the limiting portion is provided with an arc surface; the teeth on the limiting rack 42 are also provided with an arc surface.

[0081] It is worth mentioning that the above scheme provides a way to lock the support rod 2; a boss is provided on the lower side of the intercepting rod 21, and the intercepting rod 21 is squeezed and matched with the first groove 4101 through the boss, and the boss of the initial intercepting rod 21 is located at the horizontal part of the first groove 4101; a boss is provided on the lower side of the plug-in block 5, and the plug-in block 5 is squeezed and matched with the second groove 4102 through the boss, and the boss of the initial plug-in block 5 is located at the horizontal part of the lower side of the second groove 4102, and the horizontal part of the second groove 4102 and the horizontal part of the first groove 4101 provide space for the left and right movement of the sliding plate 41, so as to avoid the vibration of the device, so that the sliding plate 41 moves left and right and directly drives the plug-in block 5 to move upward, thereby locking the support rod 2; the arc surface of the limiting part of the plug-in block 5 is located on its upper side, and the arc surface of the teeth on the limiting rack 42 is located on its lower side, and the arc surfaces of the two facilitate the upward movement of the plug-in block 5 and the insertion into the limiting rack 42.

[0082] The process of the above scheme is as follows: when the plug-in block 5 drives the support rod 2 to move, the convex column of the plug-in block 5 pushes the sliding plate 41 to move synchronously, and the intercepting rod 21 also moves synchronously. During this process, if the sliding plate 41 is affected by the device and moves slightly left and right, the sliding plate 41 will not squeeze the plug-in block 5 and the intercepting rod 21 under the action of the horizontal part of the second groove 4102 and the horizontal part of the first groove 4101, thereby preventing the plug-in block 5 from moving.

[0083] When the intercepting rod 21 moves out of the pipeline, the driving motor 3 stops moving, and then the intercepting rod 21 moves upward under the action of the first elastic member 22. The intercepting rod 21 squeezes the first groove 4101 through its upper boss, and the sliding plate 41 moves, and the second groove 4102 squeezes the plug-in block 5. The plug-in block 5 moves upward under pressure, and the plug-in block 5 slides along the support rod 2 and breaks contact with the threaded rod 4.

[0084] When the plug-in block 5 moves upward, the plug-in block 5 is inserted into the limiting rack 42 through the limiting portion thereon, and the plug-in block 5 is limited by the limiting rack 42, so that the support rod 2 cannot move left and right, thereby improving the stability of the support rod 2 and preventing the support rod 2 from sliding randomly, causing the pipeline to be unable to be fixed, and then causing the pipeline to slide, thereby damaging the pipeline.

[0085] After moving the pipeline to the designated position, the sliding rod 31 and the intercepting rod 21 are pressed downward until the sliding rod 31 and the intercepting rod 21 are flush with the inner side of the support rod 2, and the user moves the U-shaped frame 1 out of the pipeline and repeats the above process to hoist the next pipeline.

[0086] In particular: Figure 3 and Fig.10As shown, it also includes: a fine-tuning mechanism, which is arranged on the U-shaped frame 1 and is used to manually adjust the center of gravity position of the U-shaped frame 1. The fine-tuning mechanism includes: a counterweight block 51, which is slidably connected to the side of the U-shaped frame 1 away from the intercepting rod 21; a rotating rod 52, which is rotatably connected to the U-shaped frame 1, and the rotating rod 52 and the counterweight block 51 are connected through a gear rack transmission.

[0087] It is worth mentioning that: the above scheme proposes a method for adjusting the center of gravity position of the U-shaped frame 1; the counterweight block 51 is a lead block, and the center of gravity of the U-shaped frame 1 is adjusted by changing the position of the counterweight block 51 so that the U-shaped frame 1 is in a horizontal state, thereby ensuring the stability of the pipeline during the lifting process; a handwheel is provided on one side of the rotating rod 52 for the user to rotate easily.

[0088] The process of the above scheme is as follows: after the pipeline is lifted, when the pipeline is off the ground, the user can adjust the position of the counterweight 51 according to the deflection direction of the U-shaped frame 1. For example, if the length of the lifted pipeline is greater than the length of the U-shaped frame 1, when the pipeline is lifted, the lifting ring 6 is at the center of gravity of the U-shaped frame 1, but the lifting ring 6 is not at the center of gravity of the pipeline, and because the pipeline is too long, the center of gravity of the pipeline is biased to the left, which will cause the U-shaped frame 1 to deflect to the left. At this time, the user can rotate the rotating rod 52, and the rotating rod 52 drives the counterweight 51 to move to the right through the gear rack, so as to balance the force of the U-shaped frame 1 and ensure the stability of the pipeline, thereby improving the applicability of the device.

[0089] In all the above schemes, the connection between the lifting ring 6 and the U-shaped frame 1 is fixed, which is consistent with the structure of the existing U-shaped clamp, that is, the lifting point of the U-shaped frame 1 cannot be changed; in all the following schemes, the lifting ring 6 and the U-shaped frame 1 are slidably connected, that is, the lifting point of the U-shaped frame 1 can be changed.

[0090] In particular: Figure 3 , Figure 4 , Fig.11 and Fig.12 As shown, it also includes: an adjusting mechanism, which is arranged on the U-shaped frame 1 and is used to control the position of the lifting ring 6. The adjusting mechanism includes: a first sleeve 61, which is fixed to the U-shaped frame 1; a pushing rod 62, which is slidably connected to the first sleeve 61 and is slidably connected to the U-shaped frame 1, the pushing rod 62 is fixed to the lifting ring 6, and the lifting ring 6 is slidably connected to the U-shaped frame 1; a driving component, which is arranged on the U-shaped frame 1 and is used to drive the pushing rod 62 to move; a detection component, which is arranged on the U-shaped frame 1 and is used to detect the distance moved by the pushing rod 62.

[0091] It is worth mentioning that: the above scheme provides a method for changing the hanging point of the U-shaped frame 1, so that the center of gravity of the U-shaped frame 1 and the pipeline can be determined by changing the position of the hanging point, and the stability of the pipeline can be further ensured; the first sleeve 61 is filled with hydraulic oil; a disc is provided in the middle of the push rod 62, and a sealing gasket is provided on the circumference of the disc to ensure the seal between it and the first sleeve 61. The hydraulic oil in the first sleeve 61 is located between the left side of the first sleeve 61 and the push rod 62. When the hydraulic oil is pumped into the first sleeve 61, the push rod 62 moves to the right (the direction is Fig.12 for example).

[0092] In particular: Figure 3 , Fig.10 and Fig.12 As shown, the driving assembly includes: a second sleeve 71, installed on the U-shaped frame 1; a pull rod 72, slidably connected to the second sleeve 71 and fixed to the support rod 2; a connecting pipe 73, fixed between the second sleeve 71 and the first sleeve 61, and the three are connected to each other.

[0093] It is worth mentioning that: the above scheme proposes a way to drive the push rod 62 to move; hydraulic oil is filled between the second sleeve 71 and the pull rod 72, and a sealing gasket is provided at the sliding connection between the pull rod 72 and the second sleeve 71 to ensure the seal between the two and avoid leakage of hydraulic oil; the connecting pipe 73 is a three-way pipe; when the pull rod 72 moves to the right, the hydraulic oil in the second sleeve 71 is pumped outward and flows through the connecting pipe 73.

[0094] In particular: Figure 3 and Figure 11-13 As shown, the detection assembly includes: a telescopic shell 81, which is arranged in the U-shaped frame 1, and the front and rear sides of the telescopic shell 81 are both telescopic plates to reflect its telescopic function; a liquid capsule 82, which is arranged in the telescopic shell 81, and the interior of the liquid capsule 82 is filled with hydraulic oil. When the hydraulic oil is pumped into it, the liquid capsule 82 will expand, and at the same time, the telescopic shell 81 and the liquid capsule 82 are attached and synchronously expand and contract with the deformation of the liquid capsule 82. The liquid capsule 82 can only expand or contract in the vertical direction. The liquid capsule 82 is fixedly connected with a detection head 83, and the detection head 83 is used to contact with the pipeline. When in contact with the pipeline After contacting the first sleeve 61, the second sleeve 71 and the liquid capsule 82, it cannot move, and the liquid capsule 82 is connected with the connecting pipe 73; the solenoid valve 84 is installed in the connecting pipe 73, and the solenoid valve 84 is used to control the flow of hydraulic oil in the connecting pipe 73, and the solenoid valve 84 is located at the connecting point of the first sleeve 61, the second sleeve 71 and the liquid capsule 82. The solenoid valve 84 is an existing three-way solenoid valve, and the solenoid valve 84 controls the second sleeve 71 to be connected with the first sleeve 61 or the liquid capsule 82 separately. At the same time, when the solenoid valve 84 is closed, the hydraulic oil in the three cannot flow to each other, thereby ensuring the stability of the three.

[0095] The process of the above scheme is as follows: during the process of hoisting the pipeline, if the length of the pipeline does not exceed the length of the U-shaped frame 1, the lifting ring 6 will not move, and the user can adjust the position of the counterweight 51 to ensure the levelness of the pipeline.

[0096] If the length of the pipeline is greater than the length of the U-shaped frame 1, the common center of gravity of the pipeline and the U-shaped frame 1 is biased to the left, and the position of the hanging point remains unchanged, resulting in the U-shaped frame 1 tilting to the left. At this time, the solenoid valve 84 is opened to connect the second sleeve 71 with the liquid capsule 82, and the support rod 2 moves to the left. During the movement of the support rod 2, the support rod 2 drives the pull rod 72 to move, and the pull rod 72 pushes the hydraulic oil in the second sleeve 71, so that the hydraulic oil in the second sleeve 71 flows along the connecting pipe 73 into the liquid capsule 82. The liquid capsule 82 begins to expand and squeezes the telescopic shell 81, so that the telescopic shell 81 opens. At the same time, the liquid capsule 82 drives the detection head 83 thereon to move downward until the detection head 83 contacts the pipeline and the detection head 83 cannot move, and the liquid capsule 82 stops expanding. At this time, the distance between the lower side of the detection head 83 and the support rod 2 is the thickness of the pipeline.

[0097] After the detection head 83 stops moving, the solenoid valve 84 blocks the connection between the second sleeve 71 and the liquid bag 82, so that the hydraulic oil cannot enter the liquid bag 82. At the same time, the solenoid valve 84 connects the second sleeve 71 with the first sleeve 61. As the pull rod 72 moves, the hydraulic oil in the second sleeve 71 gradually enters the first sleeve 61. The hydraulic oil in the first sleeve 61 drives the push rod 62 to move to the left, and the push rod 62 pushes the lifting ring 6 to move to the left, thereby adjusting the lifting point position of the U-shaped frame 1.

[0098] When the support rod 2 stops moving, the pull rod 72 stops moving, the push rod 62 stops moving, and the position adjustment of the lifting ring 6 is completed. At this time, the position of the lifting ring 6 is in the same vertical plane as the center of gravity of the pipeline and the U-shaped frame 1, so that the pipeline is in a horizontal state.

[0099] The above-mentioned detection head 83 is used to detect the wall thickness of the pipeline, and the support rod 2 is used to detect the length of the pipeline; for example: in the process of hoisting two pipelines of the same length but inconsistent wall thickness, the thicker the wall of the two pipelines, the greater its own weight, and the heavier the weight of the pipeline, the more to the left the common center of gravity position of the pipeline and the U-shaped frame 1. The thicker the wall of the pipeline, the smaller the distance moved by the detection head 83, and the less hydraulic oil in the liquid bag 82, and the more hydraulic oil in the first sleeve 61, and the greater the distance moved by the lifting ring 6. In this way, the thickness and length of the pipeline can be judged by the movement of the detection head 83 and the support rod 2, so as to know the weight of the pipeline, and then adjust the position of the lifting ring 6, so that the lifting point of the U-shaped frame 1 is always at the center of gravity, ensuring that the pipeline and the U-shaped frame 1 are in a horizontal state, thus ensuring the stability of the pipeline during the hoisting process and preventing the pipeline from slipping from the U-shaped frame 1 and causing damage to the pipeline.
