Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary tooling, and in particular relates to an auxiliary device for butting a head and a cylinder side. Background Art

[0002] The head refers to the component used to seal the end of the container to isolate the internal and external media, also known as the end cover. The head is generally connected to the cylinder by welding to form a container. The existing head welding usually adopts manual docking to complete the docking of the head and the cylinder. Generally, multiple workers need to cooperate with each other and use lifting tools such as cranes or hoists. Manual docking makes it impossible to guarantee the docking accuracy of the head and the cylinder. Generally, in order to adjust the docking accuracy of the cylinder and the head, multiple guide blocks need to be spot-welded on the cylinder first, and then the position of the head is adjusted by manual hammering. The whole process is labor-intensive, the docking accuracy of the head and the cylinder cannot be guaranteed, and it is not conducive to subsequent electric welding operations. Utility Model Content

[0022] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solutions of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0023] like Figure 1 and Figure 2As shown, an auxiliary device for docking the head and the cylinder side includes a base 1, a first support rod 2, a bracket 3, a docking frame 4 and a support assembly 5. The base 1 is a rectangular plate. The four corners of the lower end face of the base 1 are respectively connected to universal wheels 11. The universal wheels 11 are heavy-duty universal wheels with brakes. A single wheel can carry up to 230 kilograms to ensure safety during use. The four wheels drive the base 1 and the entire device to move, and the movement is limited by the brakes of the universal wheels. The first support rod 2 is set in the middle position on the base 1. The first support rod 2 uses a hydraulic telescopic rod, including a cylinder and a piston rod movably connected to the cylinder. The hydraulic telescopic rod can be an electric hydraulic telescopic rod or a manual hydraulic telescopic rod. In this embodiment, an existing manual hydraulic telescopic rod, i.e., an oil-hydraulic jack, is used. The cylinder is connected to a manual pump. When in use, the handle is inserted into the sleeve of the manual pump. The person presses back and forth, and the hydraulic oil in the cylinder causes the piston rod to rise steadily.

[0024] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the bracket 3 is connected to the top end of the piston rod of the first support rod 2. When the piston rod of the first support rod 2 moves upward, the entire bracket 3 is driven to move upward, thereby being able to adjust the upper and lower positions of the bracket 3. The bracket 3 is a rectangular frame, and the docking frame 4 is connected to one side of the bracket 3 through four connecting rods 31. The docking frame 4 is parallel to the bracket 3 as a whole. The docking frame 4 includes a first ring 41, a second ring 42, an intermediate block 43, a first adjusting bolt 44 and a second adjusting bolt 45. The first ring 41 and the second ring 42 are annular plates of the same size. The first ring 41 and the second ring 42 are arranged in parallel with a certain distance between them. The second ring 42 is arranged on the side close to the bracket 3. The intermediate block 43 is connected between the first ring 41 and the second ring 42. In this embodiment, there are eight intermediate blocks 43 (the number of intermediate blocks 43 can be multiple according to usage needs). The eight intermediate blocks 43 are distributed in an annular array. The first adjusting bolt 44 and the second adjusting bolt 45 are both threadedly connected to the intermediate block 43, and the screws of the first adjusting bolt 44 and the second adjusting bolt 45 both pass through the intermediate block 43. The heads of the two adjusting bolts are located on the outside of the ring, which is convenient for adjusting the position of the bolts by a wrench. The first adjusting bolt 44 is arranged on the side close to the second ring 42, and the second adjusting bolt 45 is arranged on the side close to the first ring 41. When in use, the first ring 41 is used to be sleeved on the outer ring of the cylinder 91, and the second adjusting bolt 45 is tightened. The screw of the second adjusting bolt 45 is pressed against the outer circumferential wall of the cylinder 91. The second ring 42 is used to be sleeved on the outer ring of the head 92, and the first adjusting bolt 44 is tightened. The screw of the first adjusting bolt 44 is pressed against the outer wall of the head 92.

[0025] like Figure 1 、 Figure 2 and Figure 4As shown, the support assembly 5 is mounted on the bracket 3 and is used to support the end cap. The support assembly 5 includes a lead screw 51, a handwheel 52, a nut block 53, and a second support rod 54. The lead screw 51 is vertically mounted in the middle of the bracket 3. Upper and lower bearings corresponding to the lead screw 51 are provided on the bracket 3, thereby rotatably connecting the lead screw 51 to the bracket 3. The handwheel 52 is connected to the top of the lead screw 51 and can be rotated by rotating the handwheel 52. The lead screw 51 is provided with threads corresponding to the nut block 53. The nut block 53 is located between the upper and lower crossbars of the bracket 3 and is movably connected to the lead screw 51. When the handwheel 52 drives the lead screw 51 to rotate, the nut block 53 moves linearly up and down along the lead screw 51. To improve the stability of the nut block 53's movement, the bracket 3 is also provided with two guide rods 55. The two guide rods 55 are symmetrically arranged on either side of the lead screw 51. The nut block 53 has through holes corresponding to the guide rods 55, thereby stabilizing the nut block 53. The second support rod 54 is connected to the nut block 53, and the second support rod 54 is connected to the side of the nut block 53 close to the docking frame 4. When in use, the second support rod 54 is inserted into the through hole of the head 92, and the nut block 53 and the second support rod 54 are raised by turning the handwheel 52, so that the second support rod 54 bears most of the weight of the head 92. The second support rod 54 and the nut block 53 are detachably connected by a threaded connection, which is convenient for using second support rods 54 of different lengths or shapes according to the different through hole sizes and positions on the head 92.

[0026] When the auxiliary device of this embodiment is in use, the head 92 is placed between the docking frame 4 and the bracket 3, with the surface of the head 92 to be welded facing outward, the second support rod 54 is inserted into the through hole of the head 92, and the hand wheel 52 is turned to make the second support rod 54 rise to support the head 92, and the multiple first adjustment bolts 44 are adjusted to make the screws press against the outer wall of the head 92, so that the head 92 is fixed and will not run, and the entire device is moved to the side of the cylinder 91 by the universal wheel, and the height of the first support rod 2 is adjusted to make the docking frame 4 and the cylinder 91 at the same height, and the entire device is moved to put the first ring 41 on the cylinder 91 On the top, the entire device is fixed by the brake of the universal wheel to prevent it from running, and multiple second adjusting bolts 45 are adjusted so that the second adjusting bolts 45 are pressed against the outer wall of the cylinder 91 to connect the docking frame 4 to the cylinder 91. According to the relative position of the cylinder 91 and the head 92, the first adjusting bolt 44 at the position to be adjusted is loosened to fine-tune the position of the head 92 so that the head 92 is aligned with the cylinder 91 to facilitate subsequent welding operations. After multiple spot weldings are performed to ensure a stable connection between the head 92 and the cylinder 91, the first adjusting bolt 44 and the second adjusting bolt 45 can be loosened to remove the entire auxiliary device.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
