Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, in particular to a cutting trolley for processing oblique cuts on a fish belly beam. Background Art

[0002] Fish belly beam refers to a beam used to support the roof or ceiling in the building structure. It is shaped like the belly of a fish and is usually located at the top or middle of houses and bridges to support and reinforce them. This beam is usually made of wood or steel and has a strong load-bearing capacity. In traditional buildings, fish belly beams are not only often used for decoration to make the building more beautiful and distinctive, but also have the characteristics of increasing bending strength and saving materials.

[0003] The fish belly beam can be understood as a bow-shaped structure, or as a reverse arch, which is the opposite of an arch bridge. Because it has an arch-shaped curvature, it requires not only straight-line cutting but also oblique cutting. Given that the precision requirements for cutting fish belly beams are relatively low, a cutting trolley is usually used to perform the cutting process on the fish belly beams.

[0004] However, when a conventional cutting trolley is processing and cutting the fish belly beam, the tail flame generated by the cutting will rush through the fish belly beam plate and impact the surface of the bracket of the fish belly beam plate, exposing the surface of the bracket to high temperature, resulting in the accumulation of local thermal stress. If the material of the bracket cannot withstand this thermal stress well, it may cause deformation, cracking or defects of the bracket, thereby affecting the structural integrity and bearing capacity of the bracket. At the same time, conventional cutting trolleys are generally equipped with linear moving guide rails, and the cutting trolley is also limited by the moving distance of the guide rails, so that the cutting trolley can only move within a specified range, or lay multiple tracks, which will increase the workload of track laying and track recycling.

[0005] Therefore, a cutting trolley for processing oblique cuts on fish belly beams is proposed. Summary of the invention

[0035] 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.

[0036] See also Figures 1 to 7 The present invention provides a technical solution for a cutting trolley for processing oblique cuts on a fish belly beam:

[0037] A cutting trolley for processing oblique cuts on a fish belly beam, comprising:

[0038] The semi-automatic flame cutting carriage 1 is mainly composed of a main body, a plasma cutting assembly and rail wheels for movement; and also includes

[0039] The follow-up flame-blocking structure 2 is arranged on the cutting side of the semi-automatic flame cutting trolley 1 and has a heat-conducting special-shaped rod, and is connected to the semi-automatic flame cutting trolley 1 through a special-shaped connecting rod;

[0040] The stacking rail 3 has multiple layers of movable rails for the cutting trolley to slide on, and the semi-automatic flame cutting trolley 1 can move on the rails, and the special-shaped rods of the follow-up flame-blocking structure 2 are in contact with the stacking rail 3 for heat conduction.

[0041] The follow-up flame-blocking structure 2 includes a waste slag recovery box 201, one side of which is fixedly provided with an electric synchronous connecting rod 202 that is bent and extended upward at a right angle, and is fixedly connected to the semi-automatic flame cutting trolley 1 through the electric synchronous connecting rod 202. The electric synchronous connecting rod 202 has several electric hydraulic rods and has the ability to adjust and extend. The waste slag recovery box 201 is composed of a square tube and a round tube, and upper wing plates 2011 are integrally provided on both sides of the upper port of the square tube, and rolling balls for assisting walking are equidistantly provided on the surface of the upper wing plates 2011. A side plate of the waste slag recovery box 201 close to the plasma cutting component is provided with an inclined slot near the upper port, and a high-temperature resistant heat-resistant fixing part 203 is inserted inside the slot and fixed by bolts, a heat-conducting plate 2031 is inserted and fixed inside the high-temperature resistant heat-resistant fixing part 203, and the inclined surface of the heat-conducting plate 2031 is attached upward on the cutting path of the bottom surface of the fish belly beam processing plate, and a heat-conducting rod 204 is fixedly provided at the center position of the bottom surface corresponding to the upper inclined surface of the heat-conducting plate 2031, and the outside of the heat-conducting rod 204 is wrapped with heat-insulating material.

[0042] When working, the semi-automatic flame cutting carriage 1 will generate a high-temperature flame to penetrate the steel plate along a specified path and flame cut the steel plate. The high-temperature waste slag and tail flame generated by the cutting will pass through the steel plate and act on the surface of the high-temperature resistant heat-resistant fixing part 203. Then the waste slag will slide along the high-temperature resistant heat-resistant fixing part 203 and the heat-conducting plate 2031 and be stored in the waste slag recovery box 201. The heat-conducting plate 2031 subjected to the high temperature will transfer the heat to the front rocker and the heat-conducting rod 204, wherein the front rocker will transfer the heat to the bottom of the steel plate to preheat the cutting path of the steel plate.

[0043] To sum up, through the arrangement of the semi-automatic flame cutting trolley 1, the waste recovery box 201, the high temperature resistant heat fixing part 203 and the heat conducting plate 2031, the tail flame and waste generated by the cutting can be thermally blocked and recovered in a follow-up manner below the cutting path, thereby avoiding damage to the bracket by the tail flame and pollution of the environment by the waste. At the same time, the recovered heat will be radiated and conducted along the heat conducting plate 2031 to the bottom surface of the cutting material, preheating the cutting path from bottom to top, which is more conducive to the cutting of the steel plate by the semi-automatic flame cutting trolley 1, can effectively reduce the time required for cutting, improve the cutting efficiency, and alleviate the problem of slow cutting of the cutting trolley to a certain extent.

[0044] As an embodiment of the present invention, Figures 5 to 7As shown, the stacking rail 3 includes a base rail 301, and a first extension rail 302 and a second extension rail 303 are sequentially arranged in a stacked manner upward on the opposite side of the semi-automatic flame cutting trolley 1 above the base rail 301. The base rail 301 and the first extension rail 302, and the first extension rail 302 and the second extension rail 303 are integrally and movably connected through a dumbbell-shaped double-ball joint rod 3014, and the upper surface of the base rail 301 and the upper surface of the first extension rail 302 are provided with a ball bar slide groove 3017 for the double-ball joint rod 3014 to slide corresponding to the shape of the double-ball joint rod 3014, and the ball bar slide groove 3017 is an S-shaped groove that is longer in the middle, facing upward near the trolley end and facing downward away from the trolley end;

[0045] Among them, the base rail 301 and the first extension rail 302 are provided with a liquid channel 3011 inside the single rail on the same side as the follower flame arrester structure 2, and a liquid push rod 3012 is slidably arranged inside the liquid channel 3011, and mercury is stored at one end of the liquid push rod 3012 inside the liquid channel 3011. The liquid push rod 3012 is located inside the liquid channel 3011 and a return spring 3013 is movably sleeved on the rod body. One end of the rod body extends out of the base rail 301 and is fixedly connected to the rail sleeve rod 3015. The rail sleeve rod 3015 is L-shaped. The sliding rod is composed of a sliding rod and a sliding sleeve for limiting the sliding rod, wherein the sliding rod is respectively fixed to the protruding end of the liquid push rod 3012 inside the first extension rail 302 and the lower side of the first extension rail 302, and the sliding sleeve is respectively fixed to the protruding end of the liquid push rod 3012 inside the base rail 301 and the upper middle side of the second extension rail 303, and a heat-conducting groove 3016 is opened in the middle position of the base rail 301 and the first extension rail 302 facing the outside of the rail, and one end of the heat-conducting rod 204 is slidably limited inside the heat-conducting groove 3016.

[0046] During operation, the heat-conducting rod 204 will move along the heat-conducting groove 3016, and the heat conducted by the heat-conducting rod 204 will be conducted to the surface of the base rail 301, and heat the mercury inside the base rail 301, and the heated mercury will expand and push the liquid push rod 3012 to move along the liquid channel 3011, and compress the return spring 3013 during the movement, and the moving liquid push rod 3012 will simultaneously push the track sleeve rod 3015, and push the first extension rail 302 to move through the track sleeve rod 3015, and then the first extension rail 302 will move along the base rail 301 in the direction away from the trolley, and during the movement, the double-ball joint rod 3014 will simultaneously slide along the ball rod groove 3017 driven by the first extension rail 302 until the first extension rail 302 moves to The end of the base rail 301, and then the first extension rail 302 will be limited by the double-ball joint rod 3014, and will be flat against each other end to end. There may also be a certain gap due to the obstruction of the double-ball joint rod 3014, and the track surface of the fallen first extension rail 302 will be flush with the base rail 301, and the liquid push rod 3012 will be in the preset space directly below the first extension rail 302, so as to achieve a one-time extension of the track. If the cutting requirement cannot be met, the heat-conducting rod 204 will move along the heat-conducting groove 3016 of the base rail 301 to the inside of the heat-conducting groove 3016 of the first extension rail 302, heat the mercury inside the first extension rail 302, cause it to expand and push the liquid push rod 3012, and finally achieve a state flush with the base rail 301 and the first extension rail 302.

[0047] To summarize, by configuring the base rail 301, the liquid channel 3011, the liquid push rod 3012, the reset spring 3013, the double-ball joint rod 3014, the rail sleeve rod 3015, the heat-conducting slide groove 3016, the ball rod slide groove 3017, the first extension rail 302 and the second extension rail 303, the heat conducted by the heat-conducting rod 204 can be coordinated with the thermal expansion force of mercury or other thermal expansion materials to realize the separate movement and drive of the first extension rail 302 and the second extension rail 303, so that they can dynamically extend the rails step by step according to the moving cutting conditions of the cutting trolley, so as to meet the movement requirements of the cutting trolley for different cutting distances. At the same time, the stacked rail setting can greatly reduce the space occupied by the rails, making it easier to use and carry.

[0048] Working principle: When working, first formulate a cutting plan according to the fish belly beam, then plan a suitable cutting path according to the plan, then arrange the stacking rail 3 on the surface of the steel plate material according to the path, and then stably place the semi-automatic flame cutting trolley 1 on the stacking rail 3, and adjust the position of the semi-automatic flame cutting trolley 1 and the follow-up flame-blocking structure 2 (waste slag recovery box 201 and electric synchronous connecting rod 202) to meet the cutting requirements of the fish belly beam. At this time, the steel plate will be between the stacking rail 3 and the follow-up flame-blocking structure 2 (the inner curved side of the electric synchronous connecting rod 202), and the follow-up flame-blocking structure 2 is directly below the cutting path of the steel plate material, and the heat conducting plate 2031 is attached to the bottom surface of the cutting path of the steel plate material, and then it can proceed. The cutting operation of the fish belly beam is performed; during the cutting process, the semi-automatic flame cutting trolley 1 will generate a high-temperature flame to penetrate the steel plate along the specified path and flame cut the steel plate, and the high-temperature waste slag and tail flame generated by the cutting will pass through the steel plate and act on the surface of the high-temperature resistant heat-resistant fixing part 203, and then the waste slag will slide along the high-temperature resistant heat-resistant fixing part 203 and the heat-conducting plate 2031 and be stored in the waste slag recovery box 201, and the heat-conducting plate 2031 subjected to the high temperature will conduct the heat to the two plate ends and the heat-conducting rod 204, wherein the plate end inclined upward and attached to the bottom of the steel plate will conduct the heat to the surface of the steel plate to preheat the cutting path of the steel plate, and the heat-conducting rod 204 will move along the heat-conducting slide groove 3016, and at the same time The heat is conducted to the surface of the base rail 301, and the mercury inside the base rail 301 is heated. The heated mercury expands and pushes the liquid push rod 3012 to move along the liquid channel 3011, and compresses the return spring 3013 during the movement. The moving liquid push rod 3012 simultaneously pushes the track sleeve rod 3015, and pushes the first extension rail 302 to move through the track sleeve rod 3015, and then the first extension rail 302 moves along the base rail 301 in the direction away from the trolley. During the movement, the double-ball joint rod 3014 simultaneously slides along the ball rod slide groove 3017 driven by the first extension rail 302 until the first extension rail 302 moves to the end of the base rail 301, and then the first extension rail 30 2 will be flatly pressed together end to end under the limitation of the double-ball joint rod 3014. There may also be a certain gap under the obstruction of the double-ball joint rod 3014, and the track surface of the dropped first extension rail 302 will be flush with the base rail 301, and the liquid push rod 3012 will be in the preset space directly below the first extension rail 302, so that the track can be extended once. If the cutting requirement cannot be met, the heat-conducting rod 204 will move along the heat-conducting groove 3016 of the base rail 301 to the inside of the heat-conducting groove 3016 of the first extension rail 302, heat the mercury inside the first extension rail 302, make it expand and push the liquid push rod 3012, and finally achieve a state of being flush with the track surface of the base rail 301 and the first extension rail 302;After the cutting is completed, the semi-automatic flame cutting carriage 1 can be manually removed, and the second extension rail 303 and the first extension rail 302 can be lifted and reset to restore them to their initial state, and then other plates can be cut. ;

[0049] It should be noted that mercury can be replaced by other suitable thermal expansion materials according to the situation; the liquid channel 3011 and the liquid push rod 3012 arranged inside the base rail 301 and the first extension rail 302 are not at the same height; the actual dimensions of the base rail 301, the first extension rail 302 and the second extension rail 303 can be designed according to actual conditions; the high-temperature heat-resistant fixing part 203 can be a fixed frame made of high-temperature resistant alloy; only the rail wheels and the double-ball joint rods are in contact between the rails, so the influence of heat conduction between the rails can be basically ignored.

[0050] 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.
