Abstract
Description
Technical Field
[0001] This utility model relates to the field of reinforced concrete pipe hoisting technology, specifically a reinforced concrete pipe hoisting device. Background Technology
[0002] In municipal engineering and building construction, reinforced concrete pipes are widely used in infrastructure construction such as drainage and gas transmission due to their high strength and durability. However, reinforced concrete pipes are usually heavy, bulky, and have a smooth surface, making their hoisting operation a critical part of the construction process, which places high demands on the stability, safety, and adaptability of the hoisting equipment.
[0003] Currently, existing reinforced concrete pipe hoisting devices require workers to pull the reinforced concrete pipe to remove it from the inside of the clamping plate after clamping it. However, larger reinforced concrete pipes require tools for handling, and the operation is only convenient after the clamping plate is moved away from the pipe. Therefore, improvements are needed. Utility Model Content
[0004] The purpose of this utility model is to provide a reinforced concrete pipe hoisting device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforced concrete pipe hoisting device, including a clamping plate, a hoisting mechanism provided on the top of the clamping plate, and a limit mechanism provided on the inner side of the hoisting mechanism;
[0006] The hoisting mechanism includes a rotating rod, which is rotatably connected to the inner side of the clamping plate. A linkage plate is rotatably connected to the outer side of the rotating rod. The linkage plate is fixedly connected to the inner side of the clamping plate. A pin is rotatably connected to the inner side of the linkage plate. A connecting plate is rotatably connected to the outer side of the pin. A limit rod is rotatably connected to the inner side of the connecting plate. A connecting rod is rotatably connected to the inner side of the connecting plate. A hoisting plate is rotatably connected to the outer side of the connecting rod.
[0007] Preferably, there are two clamping plates, which are rotatably connected to the periphery of the rotating rod. The clamping plates can clamp and fix the reinforced concrete pipe, so that the reinforced concrete pipe can be hoisted.
[0008] Preferably, there are two connecting plates, which are rotatably connected to the periphery of the pin shaft and to the periphery of the limiting rod. When the lifting rope passes through the inside of the lifting plate and pulls the lifting plate upward, the lifting plate can move the connecting plate upward through the connecting rod.
[0009] Preferably, the limiting mechanism includes a limiting plate, which is rotatably connected to the periphery of the limiting rod. A limiting slide rod is slidably connected to the inner side of the limiting plate. A fixed plate is fixedly connected to the right side of the limiting slide rod. A spring is sleeved around the periphery of the limiting slide rod. A pull plate is fixedly connected to the top of the fixed plate.
[0010] Preferably, the inner side of the limiting plate is provided with a slot corresponding to the position of the pin, and the pin is inserted into the slot. Through the slot, the limiting plate can be inserted into the pin, thereby limiting the connection plate and the linkage plate.
[0011] Preferably, the left side of the spring is fixedly connected to the inner side of the limiting plate, and the right side of the spring is fixedly connected to the left side of the fixed plate. Through the elastic force of the spring, the spring drives the fixed plate and the limiting slide rod to insert into the limiting plate to limit the pin.
[0012] Preferably, the inner side of the limiting plate is provided with a groove corresponding to the movement trajectory of the pull plate, and the pull plate is slidably connected inside the groove. Through the groove, when the worker pushes the pull plate, the pull plate drives the fixed plate and the limiting slide rod to move.
[0013] Compared with the prior art, the present invention provides a reinforced concrete pipe hoisting device, which has the following beneficial effects:
[0014] The reinforced concrete pipe hoisting device, in its hoisting mechanism, utilizes the coordinated action of components such as the rotating rod, linkage plate, and connecting plate to form a stable clamping effect on the reinforced concrete pipe. The two clamping plates are rotatably connected to the outer periphery of the rotating rod, and can adaptively adjust the clamping angle according to the outer diameter of the pipe during hoisting to ensure a tight fit with the pipe surface. This effectively avoids the risk of pipe shaking or falling off during hoisting, providing a reliable foundation for hoisting operations.
[0015] In this reinforced concrete pipe hoisting device, the limiting mechanism has a slot on the inner side of the limiting plate that corresponds to the position of the pin. When the pin is inserted into the slot, the hoisting state can be fixed. By pulling the pull plate, the fixing plate and the limiting slide rod are moved, compressing the spring, which can separate the limiting plate from the pin and release the fixed state. This allows the operator to quickly and easily complete the fixing and unlocking operations of the device, greatly improving the efficiency of hoisting operations and reducing the difficulty of operation.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0024] This utility model provides the following technical solution: Example 1
[0025] Please see Figure 1-4 The present invention provides a technical solution: a reinforced concrete pipe hoisting device, including a clamping plate 1, a hoisting mechanism 3 is provided on the top of the clamping plate 1, and a limit mechanism 2 is provided on the inner side of the hoisting mechanism 3;
[0026] The hoisting mechanism 3 includes a rotating rod 37, which is rotatably connected to the inner side of the clamping plate 1. A linkage plate 35 is rotatably connected to the outer side of the rotating rod 37. The linkage plate 35 is fixedly connected to the inner side of the clamping plate 1. A pin 36 is rotatably connected to the inner side of the linkage plate 35. A connecting plate 33 is rotatably connected to the outer side of the pin 36. A limit rod 34 is rotatably connected to the inner side of the connecting plate 33. A connecting rod 32 is rotatably connected to the inner side of the connecting plate 33. A hoisting plate 31 is rotatably connected to the outer side of the connecting rod 32.
[0027] Furthermore, there are two clamping plates 1, which are rotatably connected to the periphery of the rotating rod 37. The clamping plates 1 can clamp and fix the reinforced concrete pipe, so that the reinforced concrete pipe can be hoisted.
[0028] Furthermore, there are two connecting plates 33. The two connecting plates 33 are rotatably connected to the periphery of the pin 36, and the two connecting plates 33 are rotatably connected to the periphery of the limiting rod 34. When the lifting rope passes through the inside of the lifting plate 31 and pulls the lifting plate 31 upward, the lifting plate 31 can drive the connecting plate 33 to move upward through the connecting rod 32. Example 2
[0029] Please see Figure 1-4 Furthermore, based on Embodiment 1, the limiting mechanism 2 further includes a limiting plate 22, which is rotatably connected to the periphery of the limiting rod 34. A limiting slide rod 24 is slidably connected to the inner side of the limiting plate 22. A fixed plate 25 is fixedly connected to the right side of the limiting slide rod 24. A spring 23 is sleeved around the periphery of the limiting slide rod 24. A pull plate 21 is fixedly connected to the top of the fixed plate 25.
[0030] Furthermore, the inner side of the limiting plate 22 is provided with a slot corresponding to the position of the pin 36, and the pin 36 is inserted into the slot. Through the slot, the limiting plate 22 can be inserted into the pin 36, thereby limiting the connection plate 33 and the linkage plate 35.
[0031] Furthermore, the left side of the spring 23 is fixedly connected to the inner side of the limiting plate 22, and the right side of the spring 23 is fixedly connected to the left side of the fixed plate 25. Through the elastic force of the spring 23, the spring 23 drives the fixed plate 25 and the limiting slide rod 24 to insert into the limiting plate 22, thereby limiting the pin 36.
[0032] Furthermore, the inner side of the limiting plate 22 is provided with a groove corresponding to the movement trajectory of the pull plate 21, and the pull plate 21 is slidably connected inside the groove. Through the groove, when the staff pushes the pull plate 21, the fixed plate 25 and the limiting slide rod 24 move through the pull plate 21.
[0033] In actual operation, when this device is used for hoisting reinforced concrete pipes, the limiting rod 34 and pin 36 are first released. The operator pulls the pull plate 21, which drives the fixed plate 25 to move to the right. The fixed plate 25 then drives the limiting slide rod 24 to slide in the groove inside the limiting plate 22. At the same time, the spring 23 is compressed, which separates the limiting plate 22 from the pin 36 and releases the limiting constraints on the connecting plate 33 and the linkage plate 35.
[0034] Adjust the angle of the two clamping plates 1 to fit the outer diameter of the reinforced concrete pipe to be hoisted. When the hoisting rope passes through the hoisting plate 31 and is pulled upward, the hoisting plate 31 drives the two connecting plates 33 to move upward through the connecting rod 32. Since the connecting plates 33 are rotatably connected to the pin 36 and the limiting rod 34 respectively, and the linkage plate 35 is connected to the connecting plate 33 through the pin 36, and the linkage plate 35 is fixed on the inner side of the clamping plate 1 and rotatably connected to the rotating rod 37, the upward movement of the connecting plate 33 drives the linkage plate 35 to rotate around the rotating rod 37, thereby bringing the two clamping plates 1 closer to each other and achieving the clamping and fixing of the reinforced concrete pipe.
[0035] After the clamping plate 1 clamps the reinforced concrete pipe, the limiting plate 22 is pressed down, causing it to insert into the outer periphery of the pin 36. This allows the pin 36 to press against the limiting slide rod 24, which in turn moves the fixing plate 25 and the pull plate 21. The fixing plate 25 is then pulled by the spring 23. When the pin 36 stops pressing against the limiting slide rod 24, the spring 23 pushes the fixing plate 25 to the left under its elastic force. The fixing plate 25 then resets the limiting slide rod 24, allowing the slot inside the limiting plate 22 to reconnect with the pin 36. The limiting plate 22 then limits the pin 36, fixing the positions of the connecting plate 33 and the linkage plate 35. This prevents the clamping plate 1 from closing during its upward movement, allowing workers to remove the reinforced concrete pipe.
