[0002] In the process of prefabrication and welding of small pipe fittings and flanges, it is generally carried out on the ground or on steel plates. Due to the low height, manual bending is required to operate, which can easily cause people's fatigue. In addition, since welding is mostly overhead welding, welding on the ground or on steel plates will result in poor welding quality. For this reason, we propose a small platform for prefabricated welding brackets. Summary of the invention

[0003] The purpose of the present invention is to provide a small prefabricated welding bracket platform to solve the problem proposed in the above-mentioned background technology that welding on the ground or on a steel plate is carried out because of the low height and requires manual bending over to operate, which easily causes people to get tired, and because welding is mostly overhead welding, welding on the ground or on a steel plate will lead to poor welding quality.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a prefabricated welding bracket small platform, comprising: a bracket;

[0008] Wherein, a connecting rope for rotating the threaded sleeve is installed on the outer wall of the installation sliding block.

[0009] Preferably, a limit block is sleeved on the outer wall of the threaded push rod, an opening parallel to the mounting hole is formed on the outer wall of the mounting seat, and a guide rod connected to the limit block is slidably inserted into the inner cavity of the opening.

[0010] Preferably, an elastic support block is installed above the expansion support plate, and a receiving groove filled with air is opened inside the elastic support block.

[0011] Preferably, a second counterweight block having the same moving path as the first counterweight block is installed on the outer wall of the support plate, and a support is installed on the outer wall of the support plate.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1:

[0023] See also Figure 1 A prefabricated welding bracket small platform includes: a bracket 1, a support plate 2 and a support plate 3. The top wall of the bracket 1 is installed with the support plate 2, and the left wall of the support plate 2 is installed with the support plate 3. The support plate 3 is V-shaped and is used to expand the small platform and realize the placement and positioning of different prefabricated small components and circular small components without slipping. The small platform composed of the bracket 1, the support plate 2 and the support plate 3 is used to place the welding parts on the small platform during the welding process, so that people do not need to bend over all the time during the welding process, and a variety of welding methods (overhead welding, flat welding, downward welding, etc.) can be realized;

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A mounting groove 19 is provided on the front side wall of the support plate 2 (a mounting groove 19 may also be provided on the rear side), a mounting slider 18 is slidably inserted into the inner cavity of the mounting groove 19, and the mounting slider 18 can slide back and forth in the inner cavity of the mounting groove 19, and an expansion support plate 4 is installed on the front side wall of the mounting slider 18;

[0025] During the welding process, the expansion support plate 4 is moved forward, so that the installation slider 18 moves forward in the inner cavity of the placement groove 19, so that a gap is generated between the expansion support plate 4 and the support plate 2. During the welding process, the flange part of the welded part is placed above the expansion support plate 4, and the pipe part is placed above the support plate 2. In the process of welding between the flange and the pipe in a supine position, the gap generated between the support plate 2 and the expansion support plate 4 reduces the shielding area below the welding point between the flange and the pipe, which facilitates the welding of the pipe, and then the placed pipe and flange are welded using welding equipment;

[0026] In order to increase the stability of the small platform, a first counterweight block 6 (the first counterweight block 6 refers to a metal block, such as an iron block and a steel block, etc.) is slidably installed on the bottom outer wall of the support plate 2. The first counterweight block 6 can slide backward on the bottom wall of the support plate 2, away from the expansion support plate 4. A mounting seat 7 is installed on the bottom outer wall of the support plate 2. A mounting hole is opened on the front outer wall of the mounting seat 7. A threaded sleeve 13 is rotatably inserted into the inner cavity of the mounting hole. A threaded push rod 14 is screwed on the rear side of the inner cavity of the threaded sleeve 13. The rear end of the threaded push rod 14 is connected to the front side wall of the first counterweight block 6. A connecting rope 15 is wrapped around the outer wall of the threaded sleeve 13, and the connecting rope 15 is away from the threaded sleeve One end of 13 extends into the inner cavity of the placement groove 19 and is connected to the rear side wall of the installation slide block 18, and the outer wall of the threaded sleeve 13 is sleeved with a torsion spring, and the two ends of the torsion spring are respectively connected to the outer wall of the threaded sleeve 13 and the outer wall of the mounting seat 7, and the outer wall of the threaded push rod 14 is sleeved with a limit block 17, and the front outer wall of the mounting seat 7 is provided with an opening, and a guide rod 16 is slidably inserted into the inner cavity of the opening, and the guide rod 16 can move forward and backward in the inner cavity of the opening, and the rear end of the guide rod 16 is connected to the front side wall of the limit block 17. When the threaded sleeve 13 is rotated, the guide rod 16 slides in the inner cavity of the opening, so that the threaded push rod 14 can only move forward and backward;

[0027] During the forward movement of the expansion support plate 4, the installation slide block 18 moves forward in the inner cavity of the placement groove 19, pulling the connecting rope 15, so that the threaded sleeve 13 moves backward with the threaded push rod 14, and the first counterweight block 6 moves backward. When the expansion support plate 4 moves forward, the first counterweight block 6 moves backward to increase the weight on the rear side of the support plate 2, which is used to balance the forces on the front and rear ends of the support plate 2 to prevent the support plate 2 from tilting or tipping during the welding process. The greater the forward movement of the expansion support plate 4, the greater the backward movement of the first counterweight block 6. The installation slide block 18 is connected to the threaded sleeve 13 through the connecting rope 15, so that the threaded sleeve 13 can apply a pulling force to the installation slide block 18 through the connecting rope 15 (when the expansion support plate 4 moves forward with the installation slide block 18, exposing most of the space in the inner cavity of the placement groove 19, the contact area between the installation slide block 18 and the placement groove 19 is reduced, which will increase the pressure on the contact area between the installation slide block 18 and the placement groove 19), thereby ensuring the stability of the installation slide block 18 and the expansion support plate 4.

[0028] Embodiment 2:

[0029] See also Figure 1 , Figure 2 and Figure 4On the basis of Example 1, an elastic support block 5 made of rubber material is installed above the expansion support plate 4, a storage groove is opened inside the elastic support block 5, the inner cavity of the storage groove is filled with air, a second counterweight block 10 is slidably installed on the outer wall of the bottom of the support plate 2 (the second counterweight block 10 has the same function, the same material, and the same moving direction as the first counterweight block 6), a support is installed on the bottom wall of the support plate 2, a hole is opened on the front side wall of the support, and a mounting sleeve 8 is inserted into the inner cavity of the hole, a moving rod 9 is slidably inserted into the inner cavity of the mounting sleeve 8, and the moving rod 9 can move back and forth in the inner cavity of the mounting sleeve 8, an elastic member is installed between the front side wall of the moving rod 9 and the front side of the inner cavity of the mounting sleeve 8, the rear side wall of the moving rod 9 is connected to the front side wall of the second counterweight block 10, a connecting pipe 11 is installed between the outer wall of the mounting sleeve 8 and the bottom wall of the expansion support plate 4, the receiving groove is connected to the inner cavity of the mounting sleeve 8 through the connecting pipe 11, and the outer wall of the moving rod 9 and the inner wall of the mounting sleeve 8 are sealed to prevent the air inside the mounting sleeve 8 from accidentally leaking;

[0030] When the weight of the flange and the pipe being processed is large, the elastic support block 5 is subjected to a large gravity (the flange is placed above the elastic support block 5 during processing), which squeezes the storage groove, causing part of the air inside the storage groove to enter the inner cavity of the installation sleeve 8, so that the moving rod 9 moves backward and pushes the second counterweight block 10 backward. When the gravity exerted on the expansion support plate 4 is large, the gravity on the rear side of the support plate 2 is increased to balance the pressure exerted on both ends of the support plate 2 and prevent the support plate 2 from tilting or falling over;

[0031] A storage box 12 is installed on the outer wall of the bottom of the support plate 2, and the connecting pipe 11 passes through the storage box 12. The connecting pipe 11 is a hose. The connecting pipe 11 is pulled into the inner cavity of the storage box 12 to store the excess part of the connecting pipe 11;

[0032] See also Figure 4 and Figure 5 An elastic pad 20 made of rubber is installed on the top of the inner cavity of the placement groove 19, and the bottom wall of the elastic pad 20 is in contact with the top of the installation slider 18. An air storage tank 21 is provided inside the elastic pad 20, and the inner cavity of the air storage tank 21 is filled with air. The air storage tank 21 is connected to the inner cavity of the installation sleeve 8 through a connecting pipe;

[0033] When the gravity on the expansion support plate 4 is large, the squeezing force of the installation slide block 18 on the elastic pad 20 will increase, so that the air inside the placement groove 19 enters the inner cavity of the installation sleeve 8, which is used to move the moving rod 9 and the second counterweight block 10 to prevent the welded small platform from tilting or falling.

[0034] Compared with Example 1, components such as an elastic support block 5 and a second counterweight block 10 are added. When the gravity applied to the expanded support plate 4 is large, the gravity on the rear side of the support plate 2 is increased to balance the pressure applied to the front and rear ends of the support plate 2, thereby reducing the probability of the small platform being skewed during the welding process.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
