Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of semi-automatic assembly platform, in particular to a semi-automatic assembly platform for high-precision constant force spring support hanger. BACKGROUND

[0002] The high-precision constant force spring support hanger is a device for supporting and fixing a pipeline system, which is designed based on the principle of torque balance. Through the combination of a lever mechanism and a spring, the support hanger can maintain the balance of the load torque and the spring torque when the pipeline is displaced. Within the entire permissible load displacement range, the support force change rate of the support hanger is extremely small (usually less than 5%), thereby realizing nearly constant support force.

[0003] The existing constant force spring support hanger is mainly composed of a main spring and auxiliary springs on both sides of the main spring. Its working principle is to suspend and support the pipeline and equipment through the elastic force generated by the main spring and the auxiliary springs. Since the support force of the support hanger completely depends on the elastic force of the spring, different specifications of constant force spring support hangers need to be adapted according to the size of the pipeline and equipment. The larger the equipment, the larger the specifications of the support hanger and the internal main spring and auxiliary springs.

[0004] During the assembly process, the auxiliary springs on both sides need to be installed inside the shell, and the assembly of the main spring is carried out in the compressed state of the auxiliary springs to ensure that the auxiliary springs are always in the compressed pre-tightening state after the assembly of the main spring is completed. However, the assembly of the auxiliary springs currently usually relies on manual cooperation with a simple hydraulic mechanism for compression. This method has obvious defects: first, it is difficult to ensure that the tension of the auxiliary springs on both sides is completely consistent, resulting in insufficient assembly precision; second, this simple hydraulic mechanism is only suitable for small-sized auxiliary springs. When the constant force spring support hanger is large in size, the tension and precision of the ordinary hydraulic mechanism cannot meet the assembly requirements. If the tension of the auxiliary springs on both sides is not completely consistent during the assembly process of the constant force spring support hanger, the support hanger will have an unbalanced force problem in the initial assembly state. This imbalance will cause the main spring to be subjected to uneven pre-tightening force during assembly, thereby affecting the mechanical properties and stability of the entire support hanger. In actual operation, the support hanger is prone to tilting, shaking, or local stress concentration, which leads to uneven stress on the pipeline system, increases the risk of pipeline deformation or damage, and ultimately reduces the service life and reliability of the support hanger, and even causes safety accidents.

[0005] The prior art provides some solutions to solve the above problems, such as a high-precision constant force spring support hanger semi-automatic assembly platform and an assembly method with a publication number CN117381359B. The working principle includes the following steps: hoisting the shell to the center of the assembly platform and positioning, installing the auxiliary spring on both sides, starting the screw drive mechanism of the auxiliary spring compression device, pushing the hydraulic oil cylinder and the sliding load plate to move, and making the threaded sleeve at the front end of the pull rod contact the screw rod on the auxiliary spring mounting plate. The U-shaped support card is connected to the pull rod limiting groove through the limiting oil cylinder of the limiting bracket, the rotation motor is started to drive the pull rod and the threaded sleeve to rotate, the threaded connection of the threaded sleeve and the screw rod is completed, the limiting bracket is unlocked, the hollow sleeve piston rod of the hydraulic oil cylinder is started, the pull rod and the threaded sleeve are driven to move in the opposite direction, the auxiliary spring is compressed and uniform tension is provided, the main spring is sent into the shell assembly through the sliding oil cylinder, the tension of the hydraulic oil cylinder is released, the auxiliary spring elastic force is released and abuts on the main spring, finally, the screwing and disengagement operation of the threaded sleeve is repeated, the assembly is completed, and the sliding load plate is reset. However, although this assembly method realizes the assembly of the auxiliary spring and the main spring through a mechanical device and a hydraulic system, it has some disadvantages: first, it relies on the cooperative operation of the hydraulic oil cylinder and the screw drive mechanism, which requires high precision and synchronization of the equipment. If there is a deviation, the auxiliary spring tension will be uneven, affecting the overall performance of the support hanger; second, multiple driving sources are used in the assembly process, which requires multiple starts and switching of different driving devices, and the operation is complex and inefficient; and third, the use of the hydraulic system increases the cost and maintenance difficulty of the equipment.

[0006] Therefore, a high-precision constant force spring support hanger semi-automatic assembly platform is provided. SUMMARY

[0007] The purpose of the present application is to provide a high-precision constant force spring support hanger semi-automatic assembly platform. The existing assembly platform relies on the cooperative operation of the hydraulic oil cylinder and the screw drive mechanism, which requires high precision and synchronization of the equipment. If there is a deviation, the auxiliary spring tension will be uneven, affecting the overall performance of the support hanger. The present application realizes the synchronous compression operation of the two groups of auxiliary springs by using the movement of the rotating assembly, without the need for additional driving sources to realize this function, and can effectively control the compression force of the auxiliary spring during compression, avoiding excessive compression of the auxiliary spring.

[0010] It can be known that in the prior art, the mode of relying on hydraulic cylinder and screw rod driving mechanism to cooperate to compress auxiliary spring to install main spring has many problems: on the one hand, the mode requires high precision and synchronization of the equipment, and once deviation occurs, the auxiliary spring tension is uneven; on the other hand, the hydraulic cylinder is easily affected by factors such as hydraulic system pressure fluctuation and oil pollution during movement, resulting in decreased movement precision, and thus the tension of the auxiliary springs on both sides is not completely consistent.

[0011] In view of the above problems, the utility model provides an improved scheme, by setting a rotation subassembly, two groups of clamping rods are used to compress two groups of auxiliary springs to both sides by rotation, and in the compression process, the rotation subassembly can control the compression force, thereby effectively avoiding over-compression of the auxiliary spring and protecting the structural integrity of the auxiliary spring.

[0018] Preferably, the fixed rod is further provided with two groups of ratchets, the two groups of ratchets are symmetrically and mirror-imaged distributed, and one group of the two groups of ratchets is provided with a compression spring at the bottom; in the design stage, the selection of excessively large wire diameter, small pitch and excessive effective number of turns will cause the spring force to be too large, so that the pre-tightening force of the auxiliary spring exceeds the normal range. Therefore, the operator will use a professional force measuring device to directly measure the pre-tightening force of the auxiliary spring. The device can detect the case of excessive pre-tightening force of the auxiliary spring through the arrangement of the ratchet and the compression spring.

[0021] Compared with the prior art, the present application has the following advantages:

[0022] 1. The device uses a single drive source to drive the rotating rod, which drives the clamping rod to complete the compression operation of the auxiliary spring.

[0023] 2. By setting the rotating rod and rotating assembly, the compression force of the auxiliary spring can be effectively controlled to avoid excessive compression of the auxiliary spring, thereby ensuring the structural integrity of the auxiliary spring. The control mechanism allows the device to remain stable during assembly, reducing the risk of structural deformation or damage caused by excessive compression or uneven compression, thereby improving the stability of the entire device during use.

[0024] 3. By means of the linkage mechanism of the ratchet, compression spring and fixed rod, it can be detected whether the pre-tightening force of the auxiliary spring is appropriate during installation. Once the pre-tightening force is too large, the device will deflect the direction of the fixed rod by depressing the compression spring to ensure that only when the pre-tightening force of the auxiliary spring is appropriate, the housing can be separated from the workbench, thereby ensuring the installation quality. Reasonable pre-tightening force can avoid equipment failure caused by excessive spring force during use, improving the running stability and reliability of the equipment.
