The following is in conjunction with... Figures 1 to 4 To explain.
[0027] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.
[0028] Reference Figure 1 and Figure 2 This disclosure provides an exemplary embodiment of an auxiliary device for welding repair work inside a coal hopper car. The auxiliary device for welding repair work inside a coal hopper car includes:
[0029] The support assembly 1 includes a base 11, a side ladder 13 hinged to the base 11, a fixed seat 12 fixed to the base 11, and a support hook 14 detachably connected to the fixed seat 12. The support hook 14 is also detachably connected to the side ladder 13. There are two side ladders 13 distributed opposite to each other. The side ladder 13 can only rotate from above the base 11 to a vertical position.
[0030] The walking assembly 3 includes a downward pressing crossbar 31 hinged to the base 11, a universal wheel 32 fixed to the downward pressing crossbar 31, and a stop bar 33 fixed to the base 11. The downward pressing crossbar 31 has a first posture in which it is located above the stop bar 33 and the universal wheel 32 is located above the base 11, and a second posture in which it is located below the stop bar 33 and the universal wheel 32 is located below the base 11.
[0031] Platform component 2 includes a suspended ladder 21 for detachable connection to both side ladders 13, a partition 22 detachably connected to the suspended ladder 21 to form a storage platform, a step 23 movably connected to the side ladder 13, and a support member 24 fixed to the side ladder 13 to support the step 23 and maintain its horizontal position.
[0032] For example, refer to Figure 1 and Figure 2 The base 11 is a horizontal plate structure. There are two side ladders 13, each hinged to one end of the base 11. A limiting hinge 5 is fixed to the end of the base 11, with two limiting hinges 5 on the same end of the base 11, located on opposite sides of the base 11. The top of the limiting hinge 5 extends above the top surface of the base 11, and the bottom of the side ladder 13 extends into the top of the limiting hinge 5 and is hinged to it via a shaft. The rotation axis of the side ladder 13 is horizontal. The limiting hinge 5 restricts the position of the side ladder 13, allowing it to rotate only around a fixed axis at the end of the base 11, thus enabling it to rotate from a horizontal position against the base 11 to a vertical position.
[0033] The limiting hinge 5 consists of two plate structures that are vertically fixed to the top surface of the base 11 and spaced apart. The bottom end of the side ladder 13 extends between these two plate structures and is fixed by a shaft to achieve rotation. The limiting hinge 5 has a blocking part 51 on the side opposite to the base 11 to prevent the side ladder 13 from rotating outward from the base 11. The blocking part 51 is located above the end face of the base 11 and blocks the channel between the two plate structures laterally. That is, the limiting hinge 5 with the blocking part 51 only allows the side ladder 13 to rotate from the vertical position to the horizontal position, thereby limiting the maximum rotation angle of the side ladder 13 and providing a certain degree of support for the side ladder 13 in the vertical position.
[0034] The fixing base 12 is fixed to the top surface of the base 11 in a frame structure and is located at the center of the top surface of the base 11. The fixing base 12 has a first socket 121 for receiving the support hook 14. The first socket 121 includes a countersunk hole opened at the edge of the top surface of the fixing base 12, which extends vertically downward inside the solid structure of the fixing base 12. The side ladder 13 has a second socket 131 for receiving the support hook 14. The second socket 131 includes a sleeve fixedly connected to the side wall of the side ladder 13. In the vertical position, the axis of the sleeve is vertically set, and at this time, the sleeves on the two side ladders 13 are respectively fixed to the opposite side walls of the two side ladders 13. The support hook 14 is a rod structure with both ends bent in the same direction. By inserting the two ends of the support hook 14 into the first socket 121 and the second socket 131 respectively, the support hook 14 can be fixed between the side ladder 13 and the fixed seat 12. The side ladder 13 is fixed by the support hook 14. With the connection of the limiting hinge 5 and the blocking part 51, the side ladder 13 is kept in its current position. By replacing the support hook 14 with different lengths, different angles of the side ladder 13 can also be adapted.
[0035] Reference Figure 1 and Figure 3A pin 4 is fixed on the base 11. The pin 4 is horizontally positioned and parallel to the rotation axis of the side ladder 13. One end of the pin 4 is fixedly connected to the side wall of the base 11, and the other end extends in a direction away from the base 11. A horizontally positioned sleeve 311 is fixedly connected to one end of the pressing crossbar 31. The sleeve 311 is set perpendicular to the pressing crossbar 31 and sleeved on the pin 4, thereby enabling the pressing crossbar 31 to rotate around the pin 4. The stop lever 33 is horizontally positioned and parallel to the rotation axis of the side ladder 13. One end of the stop lever 33 is fixed to the end face of the base 11, and the other end extends outward from the side wall of the base 11 along the length of the pin 4. The pin 4, acting on the same downward pressing crossbar 31, is distributed opposite to the stop lever 33. The stop lever 33 has a positioning groove 331 below it for engaging the downward pressing crossbar 31. By removing the sleeve 311 from the pin 4, rotating the downward pressing crossbar 31, and reinstalling the sleeve 311, the position of the downward pressing crossbar 31 above and below the stop lever 33 can be changed. When the downward pressing crossbar 31 is below the stop lever 33, the downward pressing crossbar 31 is placed inside the positioning groove 331. The stop lever 33 provides both vertical and lateral limits for the downward pressing crossbar 31. At this time, the downward pressing crossbar 31 is in a horizontal position, and the caster wheel 32 protrudes from below the base 11. When the lowering bar 31 is above the stop bar 33, rotating the lowering bar 31 can make the caster wheel 32 stay above the bottom surface of the base 11, so that the base 11 can be stably placed on the ground.
[0036] The suspended ladder 21 is positioned horizontally. Four connecting rods 213 are fixed to the bottom of the suspended ladder 21, extending vertically downwards and distributed at the four pointed corners of a rectangle. The end of the side ladder 13 opposite its hinged end is recessed inwards, forming a recess 133 to accommodate the connecting rods 213. After the side ladder 13 is rotated to a vertical position, the suspended ladder 21 is installed by inserting the connecting rods 213 into the recess 133. Similarly, by using support hooks 14 of different lengths to accommodate side ladders 13 at different angles, side ladders 13 at different angles can be accommodated by using suspended ladders 21 of different lengths or by using suspended ladders 21 with different spacing between the connecting rods 213. (See additional references.) Figure 4 To meet different working conditions, one end of the suspended ladder 21 has a hook 212 that is bent into a hook shape, and the bending direction of the hook 212 is opposite to the extension direction of the connecting rod 213.
[0037] Multiple footstools 211 are fixed on the suspended ladder 21. The footstools 211 are horizontally positioned and perpendicular to the suspended ladder 21. The footstools 211 are spaced apart along the length of the suspended ladder 21. The partitions 22 are horizontally positioned on the suspended ladder 21. The ends of the partitions 22 have downwardly bent fixing parts 221 for overlapping the footstools 211. Both ends of the partitions 22 have fixing parts 221, which provide lateral limiting for the partitions 22. The fixing parts 221 can also be fastened to the footstools 211, thereby limiting the position of the partitions 22.
[0038] Similar to the suspended ladder 21, multiple climbing frames 132 are fixed on the side ladder 13. The climbing frames 132 are horizontal and perpendicular to the side ladder 13, and are spaced apart along the length of the side ladder 13. Taking the side ladder 13 in a vertical position as an example: one end of the step 23 is fitted onto the highest climbing frame 132 in the horizontal position, and the other end hangs down naturally under gravity; the support member 24 is a plate-shaped structure that is bent to the same side at both ends to form a gull-wing structure. The two ends of the support member 24 are fixed to the two sides of the side ladder 13 respectively, forming a posture that straddles the top of the side ladder 13. The bent support member 24 and the side ladder 13 form a passage for people to pass through. By rotating the step 23, the step 23 can be rotated to the top of the support member 24, and when the step 23 is in a horizontal position, it abuts against the support member 24, and the support member 24 supports the horizontally positioned step 23.
[0039] In this embodiment, the base 11 serves as the supporting foundation, the side ladder 13 supports the suspended ladder 21, the fixed seat 12 and the support hook 14 fix the side ladder 13 in an upright position, the partition 22 provides a platform for placing items, and the step 23 provides a standing platform for welding operations. By removing the support hook 14, the side ladder 13 is rotated to reduce its vertical height. The lower crossbar 31 is moved to below the stop bar 33, and the disassembled suspended ladder 21 is placed on top of the base 11, so that the base 11 can move under the action of the casters 32.
[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
