Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment disassembly and assembly technology, specifically to a puller tool. Background Technology

[0002] In the field of mechanical equipment maintenance, material conveying mechanisms in high-temperature environments such as annealing furnaces undertake continuous and high-intensity material transfer tasks. The wheels and pins, as core transmission components, bear the alternating loads generated by chain drives for extended periods, while simultaneously being continuously exposed to a complex environment of high temperatures, dust, and corrosive gases. These special operating conditions easily lead to severe wear, oxidation, corrosion, and localized thermal expansion deformation on the surfaces of the wheels and pins, causing the clearance between them to gradually disappear and form a strong adhesive state. Therefore, it is necessary to separate the wheels and pins.

[0003] In existing technologies, the separation of the wheel body and the pin shaft generally relies on manual disassembly. The wheel body is placed on the operating table, and the pin shaft is removed from the wheel body by striking it with a hammer, thus forcibly separating the two. However, this method of separation is not efficient, increases the labor intensity of the workers, and greatly reduces the efficiency of wheel removal. Utility Model Content

[0004] In view of this, the present invention provides a wheel-pulling tool that can quickly pull the pin out of the wheel body without manual removal by workers. Through the cooperation of a jack and a baffle, the pin can be pulled out quickly, reducing the labor intensity of workers and improving the wheel-pulling efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a wheel-pulling tool, including a jack, a wheel body, and a pin inserted into the center of the wheel body. A bracket is installed on the upper end of the jack, and a baffle is fixed on the upper end of the bracket. A through groove is opened on the surface of the baffle to accommodate the pin for insertion. After the wheel body is placed under the baffle, the wheel body is positioned between the baffle and the jack. The upper end of the pin passes through the through groove on the surface of the baffle, and the diameter of the through groove is smaller than the outer diameter of the wheel body. After the pin passes through the through groove, the wheel body can abut against the lower wall of the baffle. The operator holds the upper end of the pin and then presses the rocker arm of the jack, so that the jack applies an upward pushing force to the bottom end of the pin, thereby causing the pin to pass through the through groove of the baffle and be pulled out from the center of the wheel body. Thus, the pin can be quickly pulled out of the wheel body without manual removal by the operator. Through the cooperation of the jack and the baffle, the pin can be quickly pulled out of the wheel body, reducing the labor intensity of the operator and improving the efficiency of wheel pulling.

[0006] The bracket has a ring-shaped support structure, and a slot is opened on the upper side of the bracket. The operator places the wheel inside the bracket through the slot and passes the upper part of the pin through the through groove of the baffle, so that the wheel abuts against the lower wall of the baffle. The ring-shaped support mechanism makes the bracket more stable and improves the stability and reliability during operation.

[0007] The through groove on the surface of the baffle is a U-shaped groove, and the opening of the U-shaped groove faces the groove of the bracket. This allows the pin at the center of the wheel to enter simultaneously from the opening of the U-shaped groove of the baffle when the worker puts the wheel in through the groove of the bracket, making the placement process more convenient.

[0008] The baffle and the bracket are connected by welding. The welded baffle and bracket enable the baffle to withstand greater forces without being damaged, thereby improving the service life of the equipment.

[0009] The bracket and jack are detachably connected via flanges, which facilitates maintenance and upkeep of the jack, thereby extending the service life of the device.

[0010] The upper outer perimeter of the jack is equipped with a fixing ring. When installing the bracket, the bottom of the bracket is fitted with the fixing ring, and multiple through holes are evenly opened on the contact surface between the fixing ring and the bracket. After the bracket is placed on the surface of the fixing ring, the screw is passed through the through holes that coincide with the bracket and the fixing ring, and then the nut is threaded onto the screw, thereby completing the fixing of the fixing ring and the bracket.

[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0012] 1. When using this utility model, the mechanical lifting force of the jack replaces the traditional hammering, which can achieve faster and more controllable pulling out of the pin, reduce the labor intensity of the workers, and improve the pulling efficiency.

[0013] 2. When this utility model is used, the baffle and bracket are welded together, which enables the baffle to withstand greater force without being damaged, thereby improving the service life of the equipment.

[0014] 3. When this utility model is used, the ring-shaped support mechanism makes the support more stable, improving the stability and reliability during operation.

[0015] 4. When using this utility model, the flange of the bracket and the jack can be detachably connected, which facilitates the maintenance and upkeep of the jack by the staff, thereby further improving the service life of the device.

[0016] 5. When using this utility model, when the wheel is placed through the slot of the bracket, the pin at the center of the wheel can enter simultaneously from the opening of the U-shaped groove, so that the pin can abut against the inner wall of the U-shaped groove through the opening of the U-shaped groove, making the placement process more convenient.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] A type of puller tool, such as Figure 1 and Figure 2As shown: The device includes a jack 100, a wheel 400, and a pin 500 inserted at the center of the wheel 400. A bracket 200 is mounted on the upper end of the jack 100, and a baffle 300 is fixed to the upper end of the bracket 200. A through groove is formed on the surface of the baffle 300, the diameter of which is smaller than the outer diameter of the wheel 400. The through groove is large enough to accommodate the pin 500 for insertion. When the operator needs to remove the pin 500 from the wheel 400, the wheel 400 is placed under the baffle 300, positioned between the baffle 300 and the jack 100. The upper end of the pin 500 passes through the through groove on the surface of the baffle 300. At this time, the upper wall of the wheel 400 abuts against the lower surface of the baffle 300, and the output of the jack 100... The output end can contact the lower end of the pin 500. At this time, the worker holds the upper end of the pin 500 and then presses the jack 100 so that the output end of the jack 100 contacts the bottom end of the pin 500, thereby applying an upward thrust to the bottom end of the pin 500. Since the wheel 400 abuts against the lower wall of the baffle 300, the baffle 300 blocks the wheel 400, preventing the wheel 400 from moving upward with the pin 500. This allows the pin 500 to pass through the through groove of the baffle 300 and be pulled out from the center of the wheel 400. Thus, the pin 500 can be quickly pulled out from the wheel 400 without the worker having to remove it manually. Through the cooperation of the jack 100 and the baffle 300, the pin 500 can be quickly pulled out from the wheel 400, reducing the labor intensity of the worker and improving the efficiency of pulling the wheel.

[0025] Specifically, the bracket 200 is a ring-shaped support structure, and a slot 201 is provided on the upper side of the bracket 200. The operator places the wheel 400 inside the bracket 200 through the slot 201, and passes the upper part of the pin 500 through the through groove of the baffle 300. Then, the operator holds the upper part of the pin 500 so that the wheel 400 abuts against the lower wall of the baffle 300. The ring-shaped support mechanism makes the bracket 200 more stable and improves the stability and reliability during operation.

[0026] Specifically, the through groove on the surface of the baffle 300 is a U-shaped groove 301, and the opening of the U-shaped groove 301 faces the slot 201 of the bracket 200. This allows the pin 500 at the center of the wheel 400 to enter simultaneously from the opening of the U-shaped groove 301 when the worker inserts the wheel 400 through the slot 201 of the bracket 200. This allows the pin 500 to abut against the inner wall of the U-shaped groove 301 through the opening of the U-shaped groove 301, making the placement process more convenient.

[0027] according to Figure 1 and Figure 4As shown, the baffle 300 and the bracket 200 are connected by welding. Since the jack 100 will apply a large thrust to the pin 500, the same thrust will be transmitted to the baffle 300 through the wheel 400. By welding the baffle 300 and the bracket 200 together, the baffle 300 can withstand greater forces without being damaged, thereby improving the service life of the equipment.

[0028] Specifically, the bracket 200 and the jack 100 are detachably connected via flanges. This detachable connection facilitates maintenance and upkeep of the jack 100 by staff, thereby extending the lifespan of the device.

[0029] according to Figure 3 and Figure 4 As shown, a retaining ring 101 is provided on the upper periphery of the jack 100. The output end of the jack 100 passes through the inner ring of the retaining ring 101 and extends into the interior of the bracket 200. Multiple through holes are evenly provided on the surface of the retaining ring 101 that contacts the bracket 200. When installing the bracket 200, the bottom of the bracket 200 is fitted with the retaining ring 101. After the bracket 200 is placed on the surface of the retaining ring 101, the screw is passed through the overlapping through holes of the bracket 200 and the retaining ring 101, and then the nut is threaded onto the screw, thereby completing the fixing of the retaining ring 101 and the bracket 200.

[0030] It should be noted that the jack 100 is a common hydraulic jack 100 on the market. Its internal structure and working principle will not be described in detail here. Only the positional relationship and usage of the main technical features such as the bracket 200 and the baffle 300 will be described.

[0031] How to use this utility model:

[0032] When it is necessary to remove the pin 500 from the wheel 400, the worker holds the pin 500 and inserts the wheel 400 into the bracket 200 through the slot 201, and then abuts the wheel 400 against the lower wall of the baffle 300. During the insertion of the wheel 400, the pin 500 will pass through the opening of the U-shaped groove 301 and abut against the inner wall of the U-shaped groove 301. Then, the worker presses the lever of the jack 100, causing the jack 100 to... The output end pushes the pin 500 upward to apply an upward thrust to the pin 500. Since the wheel 400 abuts against the lower wall of the baffle 300, the wheel 400 cannot move upward. Thus, when the pin 500 is pushed upward by the jack 100, the pin 500 can pass through the U-shaped groove 301 and separate from the wheel 400, thereby pulling the pin 500 out of the wheel 400 without the need for manual removal by the operator, reducing labor intensity and improving the efficiency of pulling the wheel.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
