Description

Technical Field

[0001] The invention relates to the technical field of coal conveying trestle bridges, and in particular to a supporting and reinforcing device for a coal conveying trestle bridge. Background Art

[0002] The coal handling system is an important part of a thermal power plant, mainly including: a coal storage yard, a transfer station, and a coal handling trestle connecting the coal storage yard and the transfer station. The coal handling trestle mainly transports the coal delivered to the plant area to the downstream boiler through the coal handling equipment installed in the channel-shaped overhead frame structure, thereby realizing the supply of raw coal. The coal handling trestle and the transfer station are usually set at intervals, and the coal is transported from the first coal handling trestle to the first transfer station. The first transfer station transfers the coal to the second coal handling trestle, so that the coal stored in the coal storage yard is transported to the boiler for combustion in sequence; since the actual supporting structure of the coal handling trestle is mostly trough-shaped plates, it is eroded by rain and other environmental factors after long-term use. In order to improve the stability and safety of use, it is necessary to replace it to strengthen the supporting structure.

[0003] At present, when using the support reinforcement device, there is a lack of automatic carbon fiber cloth sticking mechanism. The support reinforcement of the traditional coal conveyor trestle is achieved by replacing the grooved plate. However, the traditional method of replacing the grooved plate has the problems of great difficulty, long construction period, high construction cost and labor cost. Moreover, in the process of support reinforcement operation, it is necessary to stop the operation of the equipment for construction, which not only affects the normal coal transportation demand of the electric field coal conveyor trestle belt conveyor, but also is easily restricted by the spatial environment such as the construction site and adjacent components. Therefore, a coal conveyor trestle support reinforcement device is proposed to facilitate the addition of an automatic carbon fiber cloth sticking mechanism. By adopting the carbon fiber structure reinforcement technology, the traditional reinforcement method of replacing the grooved plate can be replaced. Not only can it be carried out during the normal operation of the coal conveyor trestle, but also the construction speed is fast and there is no on-site pouring wet operation. At the same time, it can also reduce the restriction of the spatial environment such as the construction site, adjacent components, equipment, etc., thereby improving the use effect.

DETAILED DESCRIPTION

[0044] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0045] In order to facilitate the addition of an automatic carbon fiber cloth pasting mechanism, it can not only be carried out during the normal operation of the coal conveyor trestle, but also reduce the constraints of the construction site, adjacent components, equipment and other spatial environments, thereby improving the use effect, such as Figure 1-3As shown, a coal conveying trestle support reinforcement device described in the present invention comprises a moving device 1 and a reinforcement device 2, wherein the reinforcement device 2 is arranged on the top of the moving device 1, and the reinforcement device 2 comprises a mounting frame 201, a polishing assembly 3 for pre-polishing is vertically arranged on one side of the mounting frame 201, a glue brushing assembly 4 for brushing carbon fiber cloth base glue is vertically arranged on one side of the polishing assembly 3 in the mounting frame 201, a pasting assembly 5 for pasting carbon fiber cloth is horizontally arranged on one side of the glue brushing assembly 4 in the mounting frame 201, and a curing assembly 6 is vertically arranged on one side of the mounting frame 201 away from the polishing assembly 3;

[0046] The polishing assembly 3 includes two groups of vertically arranged L-shaped support frames 301, which are connected to the mounting frame 201 by bolts, and the L-shaped support frames 301 are vertically relatively fixed. The bottom of the L-shaped support frame 301 is connected to the bottom frame 302 by bolts, and the inner side of the L-shaped support frame 301 is located at the top of the bottom frame 302 and is connected to the side frame 303 by bolts. The bottom frame 302 is rotatably connected with a first polishing roller 304, and the side frame 303 is located at the top of the first polishing roller 304 and is rotatably connected with a corresponding second polishing roller 305.

[0047] When in use, through the arranged mobile device 1, polishing component 3, glue brushing component 4, pasting component 5 and curing component 6, the surface of the trough plate can be pre-polished, the carbon fiber cloth base glue is brushed, the carbon fiber cloth is automatically pasted and cured. The automatic pasting of carbon fiber cloth reinforcement method replaces the traditional construction method of replacing the trough plate, thereby solving the problems of high construction difficulty, long construction period, high construction cost and labor cost. The carbon fiber reinforcement construction is carried out during the normal operation of the coal conveyor trestle or the short-term suspension of equipment operation, and will not affect the normal coal transportation demand of the power plant coal conveyor trestle belt conveyor. The method has a fast construction speed and no on-site pouring wet operation. At the same time, it also reduces the constraints of the spatial environment such as the construction site, adjacent components, and equipment.

[0048] In order to improve the continuity of device use, for example, Figure 2 , Figure 4 As shown, the present invention also includes that the glue brush assembly 4 includes a vertically arranged first glue brush groove 401 and a horizontally arranged second glue brush groove 402, and the first glue brush groove 401 and the second glue brush groove 402 are both fixedly connected to the mounting frame 201 by bolts, and the first glue brush groove 401 is connected with a vertically arranged first glue brush roller 403 by rotation, and the second glue brush groove 402 is connected with a horizontally arranged second glue brush roller 404 by rotation, and the peripheries of the first glue brush roller 403 and the second glue brush roller 404 are both connected with bristles 405 by bonding.

[0049] When in use, after pre-polishing the surface of the trough plate supporting the coal conveyor trestle with the first glue brushing groove 401, the second glue brushing groove 402, the first glue brushing roller 403, the second glue brushing roller 404 and the bristles 405, the surface can be coated with a carbon fiber cloth base glue by rotating contact, which can not only improve the continuity of the use of the device, but also facilitate the construction efficiency and speed of the clamp reinforcement operation.

[0050] For example, Figure 6 As shown, the present invention also includes that a driving component 8 is arranged on the outside of the bottom frame 302, the driving component 8 includes a driving motor 801, and the bottom frame 302 is connected to the driving motor 801 by bolts, the outer fixed sleeve of the driving motor 801 is provided with a heat insulating sleeve 802, and the inside of the heat insulating sleeve 802 is located at the periphery of the driving motor 801 and is connected with spiral blades 803 by welding, an air inlet 804 is opened at the top of the heat insulating sleeve 802, a guide pipe 805 is arranged on one side of the heat insulating sleeve 802, and the air inlet end of the guide pipe 805 is connected to the air outlet end of the heat insulating sleeve 802.

[0051] When in use, the recovered airflow can enter the thermal insulation jacket 802 through the air inlet 804. The contact between the airflow and the outer casing of the drive motor 801 can bring the heat generated by its surface work out from the guide tube 805, thereby achieving the effect of auxiliary heat dissipation. Moreover, the setting of the spiral blades 803 can also increase the circulation range and distance of the airflow, thereby improving the heat dissipation efficiency of the drive motor 801.

[0053] The bottom of the second polishing roller 305 is connected to the second polishing roller long axis 308 by bolts, the periphery of the second polishing roller long axis 308 is connected to the second polishing roller bevel gear 309 corresponding to the first polishing roller bevel gear 307 by bolt fixing sleeve, and the first polishing roller bevel gear 307 is connected to the second polishing roller bevel gear 309 by meshing, the top of the second polishing roller 305 is connected to the second polishing roller short axis 310 by bolts, the periphery of the second polishing roller short axis 310 is fixed with a second polishing roller sprocket 311 by bolt fixing sleeve, and the bottom frame 302 and the side frame 303 are both hollow structures.

[0054] When in use, through the rotation of the first polishing roller shaft 306 and the first polishing roller bevel gear 307, the second polishing roller 305 can be driven to rotate synchronously by the meshingly connected second polishing roller bevel gear 309 and the second polishing roller long axis 308, thereby realizing the synchronous pre-polishing processing of the surface of the trough plate of the coal conveyor trestle, which has a simple structure, low cost, and is more energy-saving and stable to use.

[0055] For example, Figure 5 As shown, the present invention also includes that one end of the first rubber brush roller 403 away from the second rubber brush groove 402 is fixedly connected to the first rubber brush roller sprocket 406 through a rotating shaft bolt, and the outer periphery of the second polishing wheel sprocket 311 and the first rubber brush roller sprocket 406 is provided with a transmission chain belt 312, and the second polishing wheel sprocket 311 and the first rubber brush roller sprocket 406 are both connected to the transmission chain belt 312 through meshing;

[0057] When in use, the first rubber brush roller sprocket 406 and the transmission chain belt 312 can pre-polish the grooved plate of the coal conveyor trestle support structure, and at the same time, utilize the meshing connection method to synchronously drive the first rubber brush roller bevel gear 407 and the second rubber brush roller bevel gear 408 to rotate in relative meshing, so that the first rubber brush roller 403 and the second rubber brush roller 404 rotate synchronously, and the carbon fiber cloth base glue is brushed on the surface of the grooved plate.

[0058] For example, Figure 4 As shown, the present invention also includes that one side of the first glue brushing groove 401 and both sides of the second glue brushing groove 402 are connected with a glue spraying groove 409 by bolts, and the outer surface of the glue spraying groove 409 is provided with a base glue nozzle 410 corresponding to the first glue brushing roller 403 and the second glue brushing roller 404, and the outer side of the first glue brushing groove 401 and the bottom of the second glue brushing groove 401 are connected with a base glue groove 411 for storing carbon fiber cloth base glue by bolts.

[0059] When in use, the base glue tank 411 includes a filling port and a booster pump. The discharge end of the base glue tank 411 is connected to the glue spray tank 409 through a hose. During the brushing operation, the booster pump pressurizes the base glue tank 411, so that the carbon fiber base glue is transported to the glue spray tank 409 through the hose, and sprayed to the bristles 405 of the first glue brush roller 403 and the second glue brush roller 404 through the base glue nozzle 410, and is sprayed with glue, thereby improving the uniformity and accuracy of the base glue brushing operation.

[0060] For example, Figure 8 As shown, the present invention also includes that the pasting component 5 includes a base plate 501, both sides of the base plate 501 are connected to side plates 502 by hinges, the bottom of the base plate 501 in the mounting frame 201 is connected to a first cylinder 503 by bolts, and the output end of the first cylinder 503 is connected to the base plate 501 by bolts, the bottom of the side plate 502 in the mounting frame 201 is connected to a mounting seat 504 by bolts, the mounting seat 504 is rotatably connected to a second cylinder 505 by a rotating shaft, and the output end of the second cylinder 505 is rotatably connected to the side plate 502 by a rotating shaft, the surfaces of the base plate 501 and the side plate 502 are provided with through holes 506, and the base plate 501 and the side plate 502 are hollow structures.

[0061] When in use, the bottom of the bottom plate 501 is located between the first cylinder 503 and connected to the vacuum pump through bolts. The air inlet end of the vacuum pump is connected to the bottom plate 501 and the side plate 502 through a hose. Before reinforcing the trough-shaped plate supporting the coal conveying trestle, it is necessary to cut the carbon fiber cloth into multiple groups of strips according to the size of the trough-shaped plate in advance, and then lay the carbon fiber cloth flat on the bottom plate 501 and the side plate 502 in a horizontal state in turn. The vacuum pump is manually turned on, and the bottom plate 501 and the side plate 502 are connected through the air inlet end of the vacuum pump. The negative pressure generated by suction through the through hole 506 can suck the carbon fiber cloth strips, and assist in positioning them, thereby improving the accuracy and stability of the pasting operation. During the carbon fiber cloth pasting operation, the first cylinder 503 drives the bottom plate 501 to slide vertically upward, so that the carbon fiber cloth strips on the surface are pasted to the surface of the bottom of the supporting structure trough plate, and the second cylinder 505 drives the side plate 502 to slide upward and flip at the same time, so that the extra carbon fiber cloth strips at the bottom are pasted to the surfaces on both sides of the trough plate, and the pasting action of the carbon fiber cloth on the surface of the trough plate is completed at one time. In addition, through subsequent repeated sliding and flipping actions, the bottom plate 501 and the side plate 502 can also be used to smooth the carbon fiber cloth on the surface of the trough plate, thereby reducing bubbles generated in the gap, thereby improving the pasting and reinforcement quality.

[0062] For example, Figure 7As shown, the present invention also includes that the curing assembly 6 includes two groups of second L-shaped support frames 601 vertically arranged, the second L-shaped support frames 601 are fixedly connected to the mounting frame 201 by bolts, and the second L-shaped support frames 601 are vertically relatively fixedly arranged, the bottom of the second L-shaped support frame 601 is connected with a first curing groove 602 by bolts, the inner side of the second L-shaped support frame 601 is relatively vertically arranged with a second curing groove 603, the top of the first curing groove 602 and the outer side of the second curing groove 603 are both connected with a flow equalizing plate 604 by bolts, the surface of the first curing groove 602 is provided with a first curing groove air inlet 605, the side of the second L-shaped support frame 601 away from the second curing groove 603 is connected with a shunt pipe 606 by bolts, and the air outlet end of the shunt pipe 606 is connected to the second curing groove 603;

[0063] The air outlet end of the guide pipe 805 is connected to the air inlet 605 of the first solidification tank, and the air inlet end of the diverter pipe 606 is connected to the guide pipe 805. The first solidification tank 602 and the second solidification tank 603 are both hollow structures.

[0064] When in use, the airflow generated by heat dissipation of the drive component 8 can be utilized through the first curing groove 602 and the second curing groove 603, and transported to the surface of the grooved plate after the carbon fiber cloth is pasted through the flow equalizing plate 604, and cured, thereby improving the stability of the pasting and the quality of use.

[0065] For example, Figure 6 As shown, the present invention also includes that the bottom frame 302 and the side frame 303 are located on both sides of the first polishing roller 304 and the second polishing roller 305 are connected with a sieve plate 313 through a slot;

[0066] A dust removal and filtering assembly 7 is vertically arranged on the outer side of the L-shaped support frame 3, and the dust removal and filtering assembly 7 includes a vacuum pump 701, and the vacuum pump 701 is fixedly connected to the L-shaped support frame 301 by bolts, and the air inlet end of the vacuum pump 701 is connected to the bottom frame 302 and the side frame 303 through a pipeline, and the outer side of the L-shaped support frame 3 is located on one side of the vacuum pump 701 and is connected to the dust collecting groove 702 by bolts, and a filter plate 703 is fixedly installed in the dust collecting groove 702 through a card slot, and an air supply pipe 704 is arranged at the bottom of the dust collecting groove 702, and the air inlet end of the air supply pipe 704 is connected to the dust collecting groove 702, and the air outlet end of the air inlet pipe 704 is connected to the air inlet 804.

[0067] During use, through the suction of the vacuum pump 701, the larger particles of waste chips can be pre-screened through the sieve plate 313, and then the dust generated during the working of the polishing component 3 is pumped together with the airflow to the dust collecting tank 702, and then filtered through the dust collecting tank 702 to complete the screening, and then the airflow is connected to the air inlet 804 through the air supply pipe 704 to the drive component 8 for auxiliary heat dissipation treatment. It can not only play the role of auxiliary dust removal, but also use the filtration to carry out auxiliary heat dissipation treatment on the drive component 8 with the airflow generated by the suction vacuum, which greatly improves the functionality of use, improves the working environment quality of the device, reduces dust pollution, and is also beneficial to improve the stability of continuous operation of the drive component 8, thereby extending the service life.

[0068] For example, Fig. 9 As shown, the present invention also includes that the mobile device 1 includes a lifting platform 101, the top of the lifting platform 101 is connected to the electric slide 102 by bolts, and the output end of the electric slide 102 is connected to the bottom of the mounting frame 201 by bolts.

[0069] When in use, the reinforcement device 2 can be driven to move vertically through the lifting platform 101, and the use height of the reinforcement device 2 can be adjusted to adapt to the height of the trough plate supported by different coal conveying trestles. Through the electric slide 102, the reinforcement device 2 can be driven to move horizontally at a uniform speed and slowly by means of a screw drive, and the horizontal position of the reinforcement device 2 can be adjusted, thereby successively realizing the pre-polishing treatment of the polishing component 3, the carbon fiber cloth base glue application of the glue brushing component 4, the carbon fiber cloth bonding of the bonding component 5, and the curing treatment operations of the curing component 6, which greatly improves the continuity and flexibility of the use of the device, thereby adapting to different reinforcement positions and heights.

[0070] When the present invention is in use, the operator first moves the reinforcement device 2 to the bottom of the coal conveying trestle support structure through the lifting platform 101 of the mobile device 1, cuts the carbon fiber cloth into multiple strips according to the reinforcement range and length in advance, and then lays the cut carbon fiber cloth flat on the top of the bottom plate 501 in turn, manually turns on the vacuum pump, and uses the negative pressure generated by the vacuum pump to suck the carbon fiber cloth through the through hole 506 to limit it, then manually turns on the lifting platform 101 to drive the reinforcement device 2 to move vertically upward to support one side of the bottom of the trough plate, and then manually turns on the electric slide 102 to drive the reinforcement device 2 to slide to the bottom of the trough plate, so that the first polishing roller 304 and the second polishing roller 305 are in contact with the bottom and side of the trough plate respectively;

[0071] The driving motor 801 and the vacuum pump 701 are manually turned on. The driving motor 801 drives the first polishing roller 304 to rotate, and the bottom of the grooved plate is pre-polished. At the same time, the first polishing roller shaft 306 and the first polishing roller bevel gear 307 are driven to rotate. The first polishing roller bevel gear 307 is meshed and connected with the second polishing roller bevel gear 309, so that the second polishing roller long axis 308 and the second polishing roller 305 rotate synchronously, and the surfaces on both sides of the grooved plate are polished and ground to make the surface smoother and more perfect.

[0072] While the polishing assembly 3 is working, the electric slide 102 drives the reinforcement device 2 to slide slowly to one side at a uniform speed. Due to the rotation of the second polishing roller 305, the second polishing roller short shaft 310 and the second polishing roller 311 can drive the meshing transmission chain 312 to work. Moreover, since the transmission chain 312 is meshingly connected to the first brush rubber roller sprocket 406, it can drive the first brush rubber roller 403 to rotate, and the first brush rubber roller bevel gear 407 of the first brush rubber roller 403 is meshingly connected to the second brush rubber roller 403. The rubber roller bevel gear 408 can synchronously drive the second rubber brush roller 404 to rotate, and the booster pump in the base rubber tank 411 starts to work, and the carbon fiber cloth base rubber is transported from the base rubber tank 11 to the spraying tank 409, and sprayed from the base rubber nozzle 410 to the brush hairs 405 of the first rubber brush roller 403 and the second rubber brush roller 404. By utilizing the rotation of the first rubber brush roller 403 and the second rubber brush roller 404, the carbon fiber cloth base rubber can be applied to the surface of the grooved plate after the pre-polishing treatment is completed.

[0073] Then, under the driving action of the electric slide 102, the pasting component 5 comes to the pre-coating position of the carbon fiber cloth base glue on the grooved plate, and the first cylinder 503 and the second cylinder 503 drive the bottom plate 501 and the side plate 502 to slide upward, and the carbon fiber cloth on the bottom plate 501 is fully in contact with the carbon fiber cloth base glue applied on the surface of the grooved plate to perform an automatic pasting action. At the same time, the rotation connection between the mounting seat 504, the second cylinder 506 and the side plate 502 can drive the side plate 502 to flip upward, thereby realizing the pasting operation of the carbon fiber cloth on both sides of the grooved plate. Through the subsequent continuous repetition of the lifting, flipping and pasting actions of the bottom plate 501 and the side plate 502, not only can the pasting and reinforcement processing of the carbon fiber cloth on the grooved plate be completed, but also the pasted carbon fiber cloth can be smoothed, the bubbles generated in the pasting gap can be reduced, and the pasting and reinforcement quality can be improved;

[0074] While the carbon fiber cloth is being pasted to the trough plate supporting the coal conveying trestle for reinforcement, the vacuum pump 701 can be manually turned on. The dust generated by the pre-polishing treatment of the polishing assembly 3 together with the air can be sucked into the dust collecting tank 702 through the sieve plate 313, the bottom frame 302, and the side frame 303 by the vacuum pump 701. The dust is filtered by the filter plate 703, and the extracted airflow enters the heat insulation jacket 802 through the air supply pipe 704 and the air inlet 804. The heat generated on the outer surface of the drive motor 801 is taken out by the airflow, and is transported to the first curing tank 602 and the second curing tank 603 through the spiral blade 804, the guide pipe 805, and the diverter pipe 606. The hot airflow is blown to the outer surface of the trough plate pasted with the carbon fiber cloth by the equalizing plate 604, which can not only assist the heat dissipation of the drive motor 801, but also realize the curing of the carbon fiber cloth reinforcement structure after pasting, thereby completing the reinforcement treatment of the trough plate of the supporting structure of the coal conveying trestle at one time;

[0075] By automatically sticking carbon fiber cloth to replace the traditional support trough plate replacement reinforcement method, the difficult problems of the traditional method, such as high difficulty, long construction period, high construction cost and labor cost, are solved. In addition, the carbon fiber reinforcement construction is carried out during the normal operation of the coal conveyor trestle or the short-term shutdown of the equipment, which will not affect the normal coal transportation needs of the power plant coal conveyor trestle belt conveyor. This method has a fast construction speed and no on-site pouring wet operation. At the same time, it also reduces the constraints of the spatial environment such as the construction site, adjacent components, and equipment. It not only greatly improves the convenience and practicality of the use of the device, but also is more energy-saving and environmentally friendly, and has a high practical value.
