Description

Technical Field

[0001] The invention belongs to the technical field of precast box girders, and particularly relates to a drawing-type hydraulic internal mold demolding and cleaning device. Background Art

[0002] The integral hydraulic internal mold of precast box girders is widely used in the precast process of precast box girders because the internal mold demolding operation does not require manual entry into the concrete chamber, and the safety risk is low.

[0003] At present, the cleaning work of the mold is carried out by manual grinding. The working intensity of workers is relatively high, the working efficiency is relatively low, and the dust generated during the grinding process is likely to cause harm to the workers. In addition, when demolding is required after the precast box girder is poured, due to the excessive length and self-weight of the integral hydraulic internal mold, the difficulty of overall drawing is correspondingly increased. Moreover, in the existing production line of precast box girders, an internal mold storage area and a bottom mold rotary area need to be specially set up in sequence on one side of the pouring and curing area, which are used to store the internal mold and adjust the transportation direction of the bottom mold respectively. However, the method of separately setting up the internal mold storage area and the bottom mold rotary area increases the occupied space of the production area and reduces the site utilization rate.

[0004] Therefore, it is necessary to provide an improved technical solution for the above-mentioned deficiencies in the prior art. Summary of the Invention

[0005] The purpose of the invention is to provide a drawing-type hydraulic internal mold demolding and cleaning device to solve at least the above-mentioned technical problems existing in the prior art.

[0006] To achieve the above purpose, the drawing-type hydraulic internal mold demolding and cleaning device of the invention provides the following technical solutions:

[0007] A drawing-type hydraulic internal mold demolding and cleaning device, comprising:

[0008] A support unit for receiving and supporting the hydraulic internal mold;

[0009] A pulling unit arranged at one end of the support unit for pulling the hydraulic internal mold onto the support unit;

[0010] A cleaning unit, which includes a first cleaning mechanism for cleaning the bottom wall of the hydraulic internal mold and a second cleaning mechanism for cleaning the parts other than the bottom wall. The first cleaning mechanism is arranged at the end of the support unit away from the pulling unit. The second cleaning mechanism has a moving frame body and a cleaning component. The moving frame body is used for linearly reciprocating movement along the top of the support unit, and the cleaning component is arranged on the moving frame body for cleaning the hydraulic internal mold during the movement of the moving frame body along the support unit.

[0011] As a further optimized technical solution, the support unit has a support frame body and transverse moving wheels. The transverse moving wheels are arranged at the bottom of the support frame body and the rolling direction is perpendicular to the length extension direction of the hydraulic internal mold, so that the support unit transports the hydraulic internal mold to move laterally.

[0012] As a further optimized technical solution, the cleaning component includes:

[0013] A top mold cleaning part, which has a first cleaning brush roller. The first cleaning brush roller is rotatably arranged on the top of the moving frame body and is used for cleaning the top wall of the hydraulic internal mold;

[0014] A chamfer cleaning part, which has a second cleaning brush roller. The second cleaning brush roller is symmetrically arranged on both sides close to the top of the moving frame body and is used for cleaning the top chamfer of the hydraulic internal mold;

[0015] A side mold cleaning part, which has a third cleaning brush roller. The third cleaning brush roller is symmetrically arranged on both sides of the moving frame body and is used for cleaning the side wall of the hydraulic internal mold.

[0016] As a further optimized technical solution, the top mold cleaning part, the chamfer cleaning part and the side mold cleaning part all include position adjustment mechanisms, which are respectively used to adjust the first cleaning brush roller, the second cleaning brush roller and the third cleaning brush roller to be far from or close to the hydraulic internal mold.

[0017] As a further optimized technical solution, the first cleaning mechanism includes a fourth cleaning brush roller and a lifting adjustment structure. The lifting adjustment structure is fixedly arranged on the support unit, and the fourth cleaning brush roller is rotatably arranged on the top of the lifting adjustment structure.

[0018] As a further optimized technical solution, a conveying component for assisting the pulling unit to pull the hydraulic internal mold is arranged along the length direction at the top of the support frame body.

[0019] As a further optimized technical solution, the conveying component includes a plurality of conveying rollers. The plurality of conveying rollers are arranged at intervals on the top of the support frame body, and both ends of the conveying rollers are rotatably connected to the support frame body.

[0020] As a further optimized technical solution, a plurality of groups of limiting structures are arranged at intervals at the top of the support frame body for limiting the position of the hydraulic internal mold;

[0021] Each group of the limiting structures includes:

[0022] Clamping components symmetrically arranged on both sides of the support frame body for relatively approaching or moving away from the side wall of the hydraulic internal mold;

[0023] A linear driving component, which is fixedly arranged on the support frame body and is used for simultaneously driving the two clamping components to move;

[0024] A transmission component, which is arranged between the linear drive component and the clamping component to drive the clamping component to act.

[0025] As a further optimized technical solution, the transmission component includes a cam and a bell crank. One end of the cam is rotatably connected to the support frame body, and the other end has a chute. The linear drive component is movably connected to the chute. One end of the bell crank is connected to the cam, and the other end is connected to the clamping component.

[0026] As a further optimized technical solution, the linear drive component is a double-headed cylinder, and both ends of the double-headed cylinder are used to jointly drive the clamping component to approach or move away from the hydraulic inner mold simultaneously.

[0027] Beneficial effects: The present invention has the following remarkable advantages.

[0028] First, the pulling unit provides a powerful and stable pulling force. Combined with the structural design of the support unit, it can smoothly pull the hydraulic inner mold with a large length and self-weight onto the support unit, overcome the drawing resistance caused by self-weight and length, reduce the demolding difficulty and risk, extend the service life of the mold, and effectively solve the demolding problem.

[0029] Second, the first cleaning mechanism in the cleaning unit automatically cleans the bottom wall of the hydraulic inner mold during the process of the pulling unit pulling the hydraulic inner mold. The cleaning component of the second cleaning mechanism cleans the outer wall of the hydraulic inner mold except the bottom wall during the movement of the moving frame along the support unit. The degree of automation is high, without the need for a large amount of manual intervention, greatly reducing the labor intensity of workers, effectively avoiding the risks of low efficiency and fatigue operation caused by manual operation, making the operation process more stable and efficient, with excellent cleaning effect. Moreover, each cleaning brush has a position adjustment mechanism, which can be flexibly adjusted according to the size of the hydraulic inner mold to ensure comprehensive and dead-angle-free cleaning, effectively improving the mold cleanliness and providing a solid guarantee for the subsequent production quality of precast box girders.

[0030] Third, the device integrates the functions of demolding, cleaning, and lateral movement to adjust the position of the hydraulic inner mold. Among them, the function of adjusting the inner mold position through lateral movement can effectively avoid the equipment for adjusting the bottom mold within the bottom mold rotation area. Therefore, there is no need to separately set up an independent inner mold storage area and a bottom mold rotation area, effectively reducing the floor area of the production area, improving the utilization rate of site space, reducing the site construction and operation costs, making the production site planning of precast box girders more compact and reasonable, enhancing the economy and flexibility of the overall production system, and optimizing the layout of the site.

[0046] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0047] The shapes and sizes of the components in the drawings do not reflect the actual proportions of the products, and the purpose is only to schematically illustrate the content of the present invention.

[0048] The present invention provides a drawing-out type hydraulic internal mold demolding and cleaning device. The support unit of the drawing-out type hydraulic internal mold demolding and cleaning device is pre-arranged on one side close to the casting and curing area. The pulling unit is firmly fixed on the support unit and is connected to the hydraulic internal mold through a high-strength traction rope, so as to conveniently pull the hydraulic internal mold from the casting and curing area and store it on the support unit, solving the technical problem of difficult demolding in the prior art. At the same time, the cleaning unit is used to clean the hydraulic internal mold, with high cleaning efficiency and reduced labor intensity of manual cleaning; in addition, the support unit can transport the hydraulic internal mold to move laterally on one side of the casting and curing area, facilitating the adjustment of the hydraulic internal mold to other casting stations in the curing area, so that the position on one side of the casting and curing area can temporarily cache the hydraulic internal mold by using this device, and the position of the hydraulic internal mold can be adjusted in time through the support unit, without separately arranging a bottom mold turning area, effectively reducing the floor area of the production area and improving the utilization rate of the site space.

[0049] Embodiment 1

[0050] As Figures 1 - 10 shown, specifically refer to Figure 1 And Figure 2, The drawing and extraction type hydraulic internal mold demolding and cleaning device includes a support unit 100, a pulling unit 300 and a cleaning unit.

[0051] The support unit 100 is used to receive and support the hydraulic internal mold 200. The support unit 100 has a support frame body 110 and transverse moving wheels 120. The support frame body 110 is a frame structure made of welded steel pipes and generally in a cuboid shape. There are widened structures on both sides at the top, which are used to facilitate the placement of the hydraulic internal mold 200 and at the same time allow part of the cleaning structure of the cleaning unit to move along the top of the support frame body 110 to carry out the cleaning work.

[0052] The transverse moving wheels 120 are arranged at the bottom of the support frame body 110 and the rolling direction is perpendicular to the length extension direction of the hydraulic internal mold 200, so that the support unit 100 can carry the hydraulic internal mold 200 to move horizontally.

[0053] The pulling unit 300 is arranged at one end of the support unit 100 and is used to pull the hydraulic internal mold 200 onto the support unit 100. In this embodiment, the pulling unit 300 is a winch. The winch is fixedly installed at one end of the support frame body 110 away from the casting and curing area 700. There is a towing rope on the winch for pulling the hydraulic internal mold 200. This towing rope has sufficient tensile strength to withstand the towing requirements of the hydraulic internal mold 200.

[0054] The cleaning unit includes a first cleaning mechanism 400 for cleaning the bottom wall of the hydraulic internal mold 200 and a second cleaning mechanism 500 for cleaning the parts other than the bottom wall.

[0055] As Figure 3 、 Figure 4 shown, the first cleaning mechanism 400 is arranged at one end of the support unit 100 away from the pulling unit 300. The first cleaning mechanism 400 includes a fourth cleaning brush 410 and a lifting and adjusting structure 420. The fourth cleaning brush 410 has a rotatably arranged brush body and a driving motor arranged on one side of the brush body. The driving motor is used to drive the brush body to rotate to carry out the cleaning action.

[0056] The lifting and adjusting structure 420 is fixedly arranged on the support unit 100. The lifting and adjusting structure 420 can be selected from common electric control jacking mechanisms or hydraulic lifting mechanisms. The fourth cleaning brush 410 is rotatably arranged on the top of the lifting and adjusting structure 420, so that the cleaning height can be adjusted to suit the hydraulic internal mold 200 with inconsistent bottom wall heights. In this way, when the winch pulls the hydraulic internal mold 200 to the support frame body 110, the hydraulic internal mold 200 passes above the first cleaning mechanism 400, and the bottom wall of the hydraulic internal mold 200 can be cleaned at the same time.

[0057] As Figure 5 、 Figure 6 、 Figure 7 、Figure 8 As shown, the second cleaning mechanism 500 has a movable frame 510 and a cleaning component.

[0058] The movable frame 510 is a frame-type structure, with a channel in the middle having a size larger than the cross-sectional size of the hydraulic inner mold 200. The movable frame 510 is used to move back and forth in a straight line along the top of the support unit 100. During the movement, the movable frame 510 avoids the hydraulic inner mold 200 through the channel. The cleaning component is arranged on the inner side of the channel of the movable frame 510, and is used to clean the outer wall of the hydraulic inner mold 200 when the movable frame 510 moves along the support unit 100.

[0059] The cleaning components include a top mold cleaning portion 520 , a chamfer cleaning portion 530 and a side mold cleaning portion 540 .

[0060] like Figure 5 , Figure 6 As shown, the top mold cleaning portion 520 has a first cleaning roller brush 521 , which is rotatably disposed on the top of the movable frame 510 and is used to clean the top wall of the hydraulic inner mold 200 .

[0061] like Figure 5 , Figure 8 As shown, the chamfer cleaning part 530 has a second cleaning roller brush 531, which is symmetrically arranged on both sides near the top of the movable frame 510, and the second cleaning roller brush 531 is inclined, and the inclination angle is adapted to the chamfer of the hydraulic inner mold 200 to facilitate cleaning the top chamfer of the hydraulic inner mold 200.

[0062] like Figure 5 , Figure 7 As shown, the side mold cleaning part 540 has a third cleaning roller brush 541, and the third cleaning roller brush 541 is symmetrically arranged on both sides of the movable frame 510. The length of the third cleaning roller brush 541 is determined according to the side wall height of the hydraulic inner mold 200 to ensure that the side wall can be fully covered to facilitate cleaning of the side wall of the hydraulic inner mold 200.

[0063] At the same time, the first cleaning roller brush 521, the second cleaning roller brush 531 and the third cleaning roller brush 541 all have a rotatable roller brush body and a driving motor arranged on one side of the roller brush body, and the driving motor is used to drive the roller brush body to rotate to perform a cleaning action.

[0064] In addition, the top mold cleaning part 520, the chamfer cleaning part 530, and the side mold cleaning part 540 all include a position adjustment mechanism 550. The position adjustment mechanism 550 can be a common electric control lifting device or a hydraulic lifting mechanism, which are respectively used to adjust the first cleaning brush 521, the second cleaning brush 531, and the third cleaning brush 541 to move away from or close to the hydraulic inner mold 200. In this way, the position adjustment mechanism 550 of each cleaning part can adjust the distance between the corresponding cleaning brush and the hydraulic inner mold 200, ensuring the cleaning effect and being applicable to hydraulic inner molds 200 of different sizes.

[0065] The brush hairs of all the above cleaning brushes can be made of wear-resistant and elastic nylon materials, which can not only effectively clean the top wall but also avoid damaging the mold.

[0066] Furthermore, a conveying component 130 for assisting the pulling unit 300 to pull the hydraulic inner mold 200 is arranged along the length direction at the top of the support frame 110. In this embodiment, the conveying component 130 includes a plurality of conveying rollers. The plurality of conveying rollers are arranged at intervals on the top of the support frame 110, and both ends of the conveying rollers are rotatably connected to the support frame 110. The conveying rollers rotate smoothly under the pressure of the hydraulic inner mold 200, reducing the frictional resistance between the hydraulic inner mold 200 and the support frame 110. The spacing of the conveying rollers is designed according to the actual situation, and it is necessary to refer to the common sizes and weight distributions of the hydraulic inner molds 200 to ensure that while providing sufficient support, the hydraulic inner mold 200 is evenly stressed during movement and will not be deformed or jammed due to excessive local stress.

[0067] As Figure 9 shown, multiple groups of limiting structures 600 are arranged at intervals on the top of the support frame 110 for limiting the position of the hydraulic inner mold 200.

[0068] As Figure 10 shown, each group of limiting structures 600 includes a clamping component 610, a linear driving component 620, and a transmission component.

[0069] The clamping components 610 are symmetrically arranged on both sides of the support frame 110 for relatively approaching or moving away from the side wall of the hydraulic inner mold 200. The linear driving component 620 is fixedly arranged on the support frame 110 for simultaneously driving the two clamping components 610 to move. The transmission component is arranged between the linear driving component 620 and the clamping component 610 to drive the clamping component 610 to act.

[0070] In this embodiment, the linear driving component 620 is a double-headed cylinder, and both ends of the double-headed cylinder are used to commonly drive the clamping components 610 to simultaneously approach or move away from the hydraulic inner mold 200.

[0071] The transmission components include a cam 630 and a bell crank lever 640. One end of the cam 630 is rotatably connected to the support frame 110, and the other end has a chute 631. The linear drive component 620 is movably connected to the chute 631. One end of the bell crank lever 640 is connected to the cam 630, and the other end is connected to the clamping component 610. When the two ends of the double-headed cylinder are pushed outwards, the clamping component 610 is driven by the cam 630 and the bell crank lever 640 to move towards the hydraulic inner mold 200 to clamp the hydraulic inner mold 200( Figure 9 the state of the limit structure 600 shown by the solid line in). When the two ends of the double-headed cylinder are pulled inwards, the clamping component 610 is driven by the cam 630 and the bell crank lever 640 to move away from the hydraulic inner mold 200 to release the hydraulic inner mold 200( Figure 9 the state of the limit structure 600 shown by the dashed line in).

[0072] As Figure 11 shown, after using this device, on one side of the pouring and curing area 700 of the precast box girder production line is the bottom mold maintenance area 800. This device is arranged in the bottom mold maintenance area 800. The first cleaning mechanism 400 on the support frame 110 is installed at one end close to the pouring and curing area 700, and at the same time, the winch is installed at the end far from the pouring and curing area 700. Since the support frame 110 can move, it will not fixedly occupy space, so that the equipment in the original bottom mold rotation area can operate normally in the bottom mold maintenance area 800. That is, the bottom mold maintenance area 800 of the present invention combines the respective independent functions of the existing inner mold storage area and the bottom mold rotation area, enabling the inner mold to be stored and its position adjusted in the bottom mold maintenance area 800, and also enabling the adjustment of the bottom mold. Furthermore, it effectively reduces the floor area of the production area, improves the utilization rate of the site space, reduces the site construction and operation costs, makes the precast box girder production site planning more compact and reasonable, enhances the economy and flexibility of the overall production system, and optimizes the layout of the site.

[0073] The working principle of the present invention is as follows:

[0074] Move the support unit 100 to a suitable position so that the pulling unit 300 is aligned with the hydraulic inner mold 200 to be demolded. At this time, ensure that the transverse moving wheels 120 of the support unit 100 are in a normal rollable state, and the surface of the conveying component 130 is clean and free of obstacles to assist the subsequent movement of the hydraulic inner mold 200. Start the pulling unit 300, and the pulling unit 300 starts to pull the hydraulic inner mold 200. During the pulling process, the conveying component 130 on the support unit 100 assists the movement of the hydraulic inner mold 200. At the same time, the fourth cleaning brush 410 of the first cleaning mechanism 400 moves on the bottom wall of the hydraulic inner mold 200 to clean the bottom wall of the hydraulic inner mold 200.

[0075] After the hydraulic internal mold 200 is towed onto the support unit 100, at this time, the moving frame body 510 of the second cleaning mechanism 500 linearly reciprocates along the track 140 on the top of the support unit 100 through the moving wheels 511 at the bottom. During the movement, the first cleaning brush 521 of the top mold cleaning part 520 cleans the top wall of the hydraulic internal mold 200, and the second cleaning brush 531 of the chamfer cleaning part 530 cleans the top chamfer of the hydraulic internal mold 200; the third cleaning brush 541 of the side mold cleaning part 540 cleans the side wall of the hydraulic internal mold 200. Moreover, according to the actual size of the hydraulic internal mold 200, the position adjustment mechanism 550 of each cleaning part can be used to adjust the distance between the corresponding cleaning brush and the hydraulic internal mold 200 to ensure the cleaning effect.

[0076] After the hydraulic internal mold 200 is cleaned, it can be temporarily stored in the bottom mold maintenance area 800. When the hydraulic internal mold 200 is needed at other workstations in the pouring and curing area 700, the support unit 100 transports the hydraulic internal mold 200 to a suitable position by lateral movement.

[0077] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are within the scope of protection of the pending claims of the present invention.
