Description

Technical Field

[0001] This utility model relates to the field of heat treatment process and equipment technology, specifically to a heat treatment water tank guide device for a pump head body. Background Technology

[0002] Heat treatment is one of the key processes for improving the performance of metal parts. Water quenching is a widely used treatment method, especially common in the processing of large workpieces. This process usually requires the use of a lifting device to immerse or remove the high-temperature workpiece from the water tank. The smoothness and reliability of the lifting process directly determine the processing quality of the workpiece and the safety of the operation.

[0003] Currently, the lifting devices commonly used in heat treatment water tanks mostly adopt traditional structures such as wire rope winches or single-point hydraulic jacking. These structures have the following prominent problems in practical applications: (1) Insufficient stability: When lifting large, heavy or asymmetrical workpieces, traditional devices are prone to shaking, tilting or even jamming. This may not only cause the workpiece to collide with the tank, damaging the workpiece and affecting the uniformity of heat treatment, but also bring significant safety hazards.

[0004] (2) Poor guiding accuracy: Most devices lack high-precision guiding mechanisms, or the guide rail structure used is simple and lacks rigidity, making it difficult to effectively constrain the displacement of the lifting platform in multiple directions, resulting in inaccurate control of the running trajectory.

[0005] (3) Weak resistance to eccentric load: When faced with eccentric load conditions, the structure based on single-point drive is prone to uneven force on key transmission components such as hydraulic cylinders and chains, which will accelerate wear, shorten service life, and even cause breakage accidents.

[0006] (4) Poor environmental adaptability: The heat treatment water tank site is often accompanied by high temperature, high humidity and corrosive media. The structural parts and key components of traditional equipment are prone to thermal deformation and corrosion, which further weakens the stability of equipment operation and overall durability.

[0007] In summary, existing lifting devices are no longer sufficient to meet the requirements of high-quality heat treatment processes. There is an urgent need to develop a new type of lifting system to achieve highly stable, high-precision, safe and reliable lifting operations for heavy workpieces in water tanks. Summary of the Invention

[0008] The purpose of this invention is to provide a guiding device for a heat treatment water tank in a pump head, which improves the stability, synchronization and reliability of the lifting device in the heat treatment water tank during the lifting process, and is particularly suitable for heat treatment operations of heavy and asymmetrical workpieces.

[0009] To achieve the above objectives, the technical solution provided by this utility model is as follows: A guiding device for a heat treatment water tank for a pump head body includes a bracket, a lifting drive mechanism, a lifting platform, and a guiding mechanism. The bracket is a rigid frame structure fixed above the heat treatment water tank. The lifting drive mechanism is mounted on the bracket, and the lifting platform is located below the bracket. The output end of the lifting drive mechanism is connected to the lifting platform, and a guiding mechanism is provided between the bracket and the lifting platform. The lifting platform is provided with a lifting lug that cooperates with the lifting drive mechanism, and the pump head body to be treated is loaded on the lifting platform. The guiding mechanism includes an H-shaped guide rail and a guide shoe. The guide shoe and the flange of the H-shaped guide rail are in sliding fit, and the guide shoe is fixed to the side of the lifting platform.

[0010] To optimize the above technical solution, the specific limitations also include: The bracket is fixedly installed on the upper edge of the heat treatment water tank.

The lifting drive mechanism is installed on the horizontal bar, and the H-shaped guide rail is fixedly installed on the vertical columns. The H-shaped guide rail is parallel to the vertical columns.

[0011] Alternatively, the lifting drive device includes a drive motor and a drum driven by the drive motor, with a wire rope or chain wound on the drum. One end of the wire rope or chain is connected to a lifting lug provided on the lifting platform. The drive motor is used to drive the drum to rotate, thereby raising or lowering the lifting platform via the wire rope or chain.

[0012] Preferably, the lifting drive device includes a drive motor, a lead screw, and a lead screw nut. The lead screw nut is installed on the lifting lug of the lifting platform. Preferably, the lead screw and the lead screw nut are connected in a mating manner. The drive motor is used to drive the lead screw to rotate, thereby raising or lowering the lifting platform.

[0013] Preferably, the lead screw is rotatably mounted between the bracket and the bottom of the heat treatment tank via a bearing seat.

[0014] Preferably, the fit clearance between the inner end face of the guide shoe and the flange of the H-shaped guide rail is 20~30mm.

[0017] Preferably, the vertical column of the support is provided with a limiting point, and a position sensor is installed at the limiting point to limit the travel of the lifting platform.

[0018] Preferably, the guide shoe has a concave block structure, and the flange of the H-shaped guide rail fits into the concave shape of the guide shoe.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This invention provides a guiding device for a heat treatment water tank in a pump head. The main guiding mechanism of this device employs an H-shaped guide rail and guide shoes, forming a large-area, high-rigidity sliding pair. This effectively constrains the various degrees of freedom of the lifting platform during operation, completely eliminating swaying and tilting, and ensuring absolutely vertical and stable lifting. Simultaneously, the H-shaped guide rail itself possesses extremely high bending and torsional stiffness. Fixing its bottom to the bottom of the water tank further enhances the rigidity of the entire support system, making guidance more precise and improving resistance to eccentric loads. This device also incorporates limit position sensors to achieve automatic limit protection, preventing mechanical overshoot damage and ensuring safe and reliable operation.

[0024] The present invention will be further described in detail below through specific embodiments. However, it should not be construed as the scope of the present invention being limited to the following embodiments. All technologies implemented based on the present invention fall within the scope of the present invention.

[0025] The technical solution of this utility model will be further described in detail below with reference to specific embodiments: This utility model provides a guide device for a heat treatment water tank for a pump head body, including a bracket 3, a lifting drive mechanism, a lifting platform 1 and a guide mechanism; like Figure 1 As shown, the support 3 is a rigid frame structure fixed above the heat treatment water tank 2; a lifting drive mechanism is installed on the support 3, and a lifting platform 1 is provided below the support 3. The output end of the lifting drive mechanism is connected to the lifting platform 1, and a guide mechanism is provided between the support 3 and the lifting platform 1. In some embodiments, the lifting platform 1 is provided with a lifting lug 6 that cooperates with the lifting drive device, and the pump head body to be processed is loaded on the lifting platform 1.

[0026] like Figure 2 and Figure 3 As shown, the guiding mechanism includes an H-shaped guide rail 4 and a guide shoe 5. The guide shoe 5 and the flange of the H-shaped guide rail 4 are in a sliding fit. The guide shoe 5 is fixed to the side of the lifting platform 1. The guide shoe 5 has a concave block structure. The flange of the H-shaped guide rail 4 and the concave shape of the guide shoe 5 fit together to form a high-precision sliding pair. The concave block structure of the guide shoe is made of wear-resistant material to improve its service life.

[0027] The fit clearance between the inner end face of the guide shoe 5 and the flange of the H-shaped guide rail 4 is 20~30mm to ensure smooth sliding without shaking.

[0028] The bracket 3 is fixedly installed on the upper edge of the heat treatment water tank 2. The bracket 3 includes a horizontal bar at the top and vertical columns on both sides of the horizontal bar. The main body of the bracket 3 is welded from steel profiles and has sufficient rigidity and strength.

[0029] The lifting drive mechanism is installed on the horizontal bar, and the H-shaped guide rail 4 is fixedly installed on the vertical column. The H-shaped guide rail 4 is parallel to the vertical column. The bottom of the H-shaped guide rail 4 is installed at the bottom of the heat treatment water tank 2 through the fixing seat. The double fixing support method enhances the rigidity and stability of the entire frame structure, so that the device can remain stable even when carrying heavy objects or having an off-center load, ensuring that the lifting platform is absolutely vertical and operates smoothly.

[0030] This utility model provides two drive solutions: a lead screw nut and a wire rope drum, suitable for different working conditions. In some embodiments, the lifting drive device includes a drive motor and a drum driven by the drive motor, with a wire rope or chain wound on the drum. One end of the wire rope or chain is connected to a lifting lug 6 provided on the lifting platform 1. The drive motor is used to drive the drum to rotate, thereby raising or lowering the lifting platform 1 through the wire rope or chain.

[0031] Alternatively, the lifting drive device includes a drive motor, a lead screw, and a lead screw nut. The lead screw nut is installed on the lifting lug 6 of the lifting platform 1, and the lead screw and lead screw nut are connected in a mating manner. The lead screw is rotatably installed between the bracket 3 and the bottom of the heat treatment water tank 2 through a bearing seat. When the drive motor drives the lead screw to rotate in both directions, the lead screw nut drives the lifting platform 1 to make a precise vertical lifting and lowering movement along the axis of the lead screw, thereby further raising or lowering the lifting platform 1.

[0032] In some embodiments, there are two H-shaped guide rails 4 on each side of the support 3, and two guide shoes 5 and two lifting lugs 6 on each side of the lifting platform 1. The H-shaped guide rails 4, guide shoes 5 and lifting lugs 6 are symmetrically installed on both sides of the support platform 1 to ensure that the lifting platform 1 can be raised and lowered smoothly and vertically.

[0033] Preferably, the lifting platform 1, guide shoe 5, lifting lug 6, and fasteners in contact with the medium are all made of high-strength and corrosion-resistant stainless steel, which has high strength, high hardness and excellent corrosion resistance, and is fully adaptable to the harsh working conditions of the heat treatment water tank, ensuring the long service life and reliability of the device, thereby improving the environmental adaptability of the device.

[0034] The vertical column of the support frame 3 is equipped with limit points, and a position sensor is installed at the limit point to limit the stroke of the lifting platform 1. The automatic stroke limit protection avoids mechanical overshoot damage and ensures safe and reliable operation.

[0035] To better understand this utility model, its usage is described as follows: The support frame is driven by a drive device to rise to the top of the coolant level in the heat treatment tank, and the 15-5PH pump head body to be heat-treated is placed on the lifting platform 1 for fixation. The drive device is then operated to control the lifting platform 1 to descend into the heat treatment tank for heat treatment. After the heat treatment is completed, the lifting platform 1 is raised again to remove the heat-treated 15-5PH pump head body. During the lifting process of the lifting platform 1, the drive device provides power through screw rotation or wire rope winch. Lifting lugs are provided on both sides of the lifting platform 1 to ensure stable ascent. In addition, the H-shaped guide rail 4 and guide shoe 5 limit the degree of freedom of movement of the lifting platform 1, allowing it to move only vertically up and down. This completely eliminates the shaking, tilting, and jamming problems common in traditional lifting devices, ensuring that the lifting platform operates absolutely vertically and smoothly, thereby guaranteeing the consistency and high quality of the workpiece heat treatment process.

[0036] This device utilizes H-type guide rails 4, providing superior bending and torsional resistance. Its bottom-fixed design within the water tank creates a double-fixed support frame, enhancing overall rigidity. Even under heavy or off-center loads, the system maintains stable operation, demonstrating excellent anti-interference and posture stability. It offers both screw-driven and wire rope winch-driven options to meet diverse needs. Automatic travel limit protection via limit sensors mitigates mechanical overshoot risks, ensuring safe and controllable operation. Furthermore, the materials used for core components exposed to high temperatures, high humidity, and corrosive media enable the device to withstand the harsh conditions of the water tank, fundamentally avoiding the corrosion and wear issues common with conventional materials, reducing failure frequency and maintenance costs, and effectively extending the equipment's service life.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made by those skilled in the art to the above embodiments without departing from the scope of the present utility model's technical solution and based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model's technical solution.
