Abstract
Description
Technical Field
[0001] This utility model relates to the field of head alignment assistance technology, specifically a head alignment assistance device. Background Technology
[0002] An end cap is a component used to seal the end of a container, isolating it from the internal and external media. Cylindrical end caps are generally rotating shells. Based on the shape of their surface, end caps can be classified as convex, conical, flat, and combined types. Convex end caps are those with a convex outer surface, such as hemispherical, elliptical, dished, and edgeless spherical end caps. Some gas cylinders use combined bottom end caps with a convex inward surface, ensuring both strength and safety. An end cap is a component of a container, connected to the cylindrical body by welding, and is used in various container equipment such as storage tanks, heat exchangers, towers, reactors, boilers, and separation equipment.
[0003] Currently, when welding end caps to tank bodies, the end caps are clamped and fixed. The position of the clamping mechanism is fixed and cannot be adjusted, making it difficult to align and calibrate the end caps with the tank body. Therefore, an end cap alignment auxiliary device is proposed to solve the above-mentioned problems. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a head alignment auxiliary device to address the shortcomings of the prior art.

[0006] The adjustment mechanism includes a fixed frame, an adjustment seat slidably connected inside the fixed frame, a threaded column rotatably connected inside the fixed frame via a bearing, the adjustment seat being threadedly connected to the threaded column, a slide rod fixedly connected inside the fixed frame, the adjustment seat being slidably connected to the slide rod, a first hydraulic cylinder fixedly connected inside the support base, the fixed frame being fixedly connected to the telescopic end of the first hydraulic cylinder, and a guide rod fixedly connected to the bottom of the fixed frame.
[0007] Preferably, the support base has a guide hole, the guide rod is inserted into the guide hole, and a throttle is fixedly connected to the threaded post. The guide hole and the guide rod can guide the fixed frame.
[0008] Preferably, there are two guide rods, which are fixedly connected to the bottom ends of the fixing frame. The adjusting seat has an internal threaded hole, and the threaded column is threaded into the inside of the internal threaded hole. The front and rear positions of the adjusting seat can be adjusted by rotating the threaded column.
[0009] Preferably, the motor is fixedly connected to the adjusting seat, the turntable has a guide groove, and a cylinder is fixedly connected inside the guide groove. The turntable can be rotated by starting the motor.
[0010] Preferably, the telescopic end of the cylinder is fixedly connected to a clamping plate, and there are three clamping plates. The three clamping plates are equally spaced on the turntable, and the end cap is located between the three clamping plates. The clamping plates can clamp and fix the end cap.
[0011] Preferably, the turntable is provided with an abutting mechanism, which includes a second hydraulic cylinder. A pressing head is fixedly connected to the telescopic end of the second hydraulic cylinder. The abutting mechanism can provide limiting support for the end cap.
[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:
[0013] 1. This end cap alignment auxiliary device involves placing the end cap between three clamping plates and activating a cylinder to clamp and fix the end cap. When alignment is required during the docking of the end cap with the tank body, the user can activate the first hydraulic cylinder to adjust the position and height of the fixing frame, thereby adjusting the position and height of the end cap. When the front-to-back position of the end cap needs to be adjusted, the operator can turn the handle to rotate the threaded column, allowing the adjusting seat to move back and forth along the slide rod, thereby achieving the purpose of adjusting the front-to-back position of the end cap. This facilitates rapid alignment of the end cap and improves the accuracy of docking between the end cap and the tank body.
[0014] 2. This head positioning auxiliary device moves the pressure head by activating the second hydraulic cylinder, so that the pressure head abuts against the head, which can support the head and prevent displacement of the head due to contact with the tank body, thus further improving the practicality of the auxiliary device.

[0026] The adjusting mechanism 2 includes a fixed frame 201, an adjusting seat 204 slidably connected inside the fixed frame 201, a threaded column 202 rotatably connected inside the fixed frame 201 via a bearing, the adjusting seat 204 threadedly connected to the threaded column 202, a sliding rod 203 fixedly connected inside the fixed frame 201, the adjusting seat 204 slidably connected to the sliding rod 203, a first hydraulic cylinder 207 fixedly connected inside the support base 1, the fixed frame 201 fixedly connected to the telescopic end of the first hydraulic cylinder 207, and a guide rod 205 fixedly connected to the bottom of the fixed frame 201. This allows the end cap 9 to be placed between the three clamping plates 8. The cylinder 6 is activated so that its clamping plate 8 clamps and fixes the end cap 9. When the end cap 9 needs to be aligned during the docking process with the tank body, the user can activate the first hydraulic cylinder 207 to adjust the position and height of the fixing frame 201, thereby adjusting the position and height of the end cap 9. When the end cap 9 needs to be adjusted in the front and back position, the operator can turn the handle 206 to drive the threaded column 202 to rotate, so that its adjusting seat 204 can move back and forth along the slide rod 203, thereby achieving the purpose of adjusting the front and back position of the end cap 9, which facilitates the quick alignment of the end cap 9 and improves the accuracy of the docking between the end cap 9 and the tank body.
[0027] The support base 1 has a guide hole 208, and the guide rod 205 is inserted into the guide hole 208. The threaded post 202 is fixedly connected to the handle 206. The guide hole 208 and the guide rod 205 can guide the fixed frame 201.

When the end cap 9 needs to be aligned during docking with the tank, the user can activate the first hydraulic cylinder 207 to adjust the position and height of the fixing frame 201, thereby adjusting the position and height of the end cap 9. When the end cap 9 needs to be adjusted in the front and back position, the operator can turn the handle 206 to drive the threaded column 202 to rotate, allowing the adjusting seat 204 to move back and forth along the slide rod 203, thereby achieving the purpose of adjusting the front and back position of the end cap 9, facilitating the quick alignment of the end cap 9 and improving the accuracy of docking between the end cap 9 and the tank.
