Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, and in particular to a box beam inner mold grinding device and a use method thereof. Background Art

[0002] The main function of the box girder inner formwork is to maintain the shape and structure of the concrete during pouring, provide necessary support to prevent deformation, improve the surface quality of the inner wall, simplify the construction process and prevent concrete leakage, thereby ensuring the overall quality and safety of the box girder;

[0003] After the pouring operation is completed, the inner mold of the box girder releases the supporting state by shrinking and deforming, thereby completing demoulding. During the demoulding process, part of the concrete will adhere to the surface of the inner mold. Before the inner mold is used for the next pouring, the surface of the inner mold needs to be polished and cleaned to restore the surface of the inner mold to a smooth state to prevent the residual concrete from the last time from affecting the forming of the concrete during the next pouring. Since the specifications of the two ends and the middle of the box girder inner mold are inconsistent, it is difficult for the cleaning equipment with fixed specifications to be adaptively adjusted according to the specifications of the inner mold. When cleaning, it mainly relies on increasing the diameter of the grinding roller to match the shape of the box girder inner mold. This method will cause the grinding roller to have inconsistent strength when grinding the two ends and the middle of the box girder inner mold, which will lead to excessive wear of one end of the grinding roller and poor grinding effect of the other end.

[0016] A method for using a box beam inner mold grinding device comprises the following steps:

[0017] Step A, preparation before operation;

[0018] Step B, job status switching;

[0019] Step C, polishing of the inner mold of the box girder.

[0020] Preferably, the step A comprises:

[0021] Step A1, control the movable end of the hydraulic rod to move upward, the movable end of the hydraulic rod moves upward to drive the multi-end reducer to move upward along the guide slideway, and the two sets of multi-end reducers that move upward drive the main grinding roller to move upward synchronously until the height of the main grinding roller exceeds the height of the top of the box beam inner mold, at which time the main grinding roller is in an operation ready state;

[0022] Step A2, during the upward movement of the multi-end reducer, the transmission assembly at the bottom of the multi-end reducer synchronously moves upward to adjust its own setting position. During the upward movement of the transmission assembly, the connection position of the transmission assembly and the upper end of the side transmission rod synchronously moves upward. Due to the upward movement of the upper end of the side transmission rod, under the elastic force of the return spring, the sliding connection seat moves horizontally along the adjustment slideway toward the traveling base. The lower end of the side transmission rod is synchronously adjusted in coordination with the adjustment of the position of the upper end. The side transmission rod is turned from a large inclination angle to a small inclination angle. At this time, the side grinding roller arranged on the side transmission rod is in a ready state for operation.

[0023] Step A3, the traveling base drives the gantry, the grinding power assembly, the main grinding roller and the follow-up adjustment assembly to move horizontally until they move to one end of the box beam inner mold;

[0024] The step B comprises:

[0025] Step B1, control the movable end of the hydraulic rod to move downward, the movable end of the hydraulic rod moves downward to drive the multi-end reducer to move downward along the guide slideway, and the two sets of multi-end reducers moving downward drive the main grinding rollers to move downward synchronously. During the downward movement, the main grinding rollers gradually approach the top of the box beam inner mold, and deform after the main grinding rollers contact the top of the box beam inner mold. The deformation area of ​​the main grinding rollers is the grinding and cleaning area of ​​the top of the box beam inner mold;

[0026] Step B2, during the downward movement of the multi-end reducer, the transmission assembly at the bottom of the multi-end reducer synchronously moves downward to adjust its own setting position. During the downward movement of the transmission assembly, the connection position of the transmission assembly and the upper end of the side transmission rod synchronously moves downward. Due to the downward movement of the upper end of the side transmission rod, the lower end of the side transmission rod pushes the sliding connection seat through the connecting sleeve to move laterally along the adjustment slideway in the direction away from the traveling base. The lower end of the side transmission rod is synchronously adjusted in coordination with the adjustment of the position of the upper end. The side transmission rod is turned from a small inclination angle to a large inclination angle. At this time, the side grinding roller arranged on the side transmission rod is deformed after contacting with the side wall of the box beam inner mold. The deformation area of ​​the side grinding roller is the grinding and cleaning area of ​​the side wall of the box beam inner mold. At the same time, the guide plate at the upper end of the side transmission rod contacts the side wall of the box beam as the inclination angle of the side transmission rod changes;

[0027] The step C comprises:

[0028] Step C1, controlling the rotation of the servo motor through an external switch, the servo motor drives the multi-end reducer to work, and the two sets of multi-end reducers cooperate to drive the main grinding roller to rotate, and the rotating main grinding roller grinds the top of the box beam inner mold;

[0029] Step C2, two sets of multi-end reducers cooperate to drive the transmission assembly to rotate, the transmission assembly synchronously drives the side transmission rod to rotate through the Hooke hinge, and the side grinding roller installed outside the side transmission rod grinds the side wall of the box beam inner mold;

[0030] Step C3, the traveling base moves at a constant speed, and the moving traveling base drives the grinding power assembly, the main grinding roller, the follow-up adjustment assembly and the side grinding roller to move horizontally from one end of the box beam inner mold to the other end of the box beam inner mold through the gantry;

[0031] Step C4, during the lateral movement of the grinding power component and the follow-up adjustment component, the guide plate maintains contact with the box beam inner mold. During the movement from the end of the box beam inner mold to the middle of the box beam inner mold, due to the gradual increase in the diameter of the box beam, the guide plate can keep the side transmission rod at a fixed distance from the side wall of the box beam inner mold by contact during the lateral movement. During this process, the upper end of the side transmission rod is pushed by the guide plate, and the upper end of the side transmission rod moves downward. The transmission inner rod cooperates with the downward movement of the upper end of the side transmission rod and moves downward along the transmission outer rod to maintain normal power transmission. The lower end of the side transmission rod further pushes the sliding connection seat to move horizontally along the adjustment slide through the connecting sleeve, and the return spring continues to extend and tighten under the pull of the sliding connection seat.

[0032] Step C5, after the guide plate contacts the middle of the side wall of the box beam inner mold, the inclination angle of the side transmission rod is fixed, and the side grinding roller installed outside the side transmission rod is kept at a fixed working angle;

[0033] Step C6, similarly, after the guide plate contacts the other end of the box beam inner mold side wall, the inclination angle of the side transmission rod is gradually restored until it returns to the initial working preparation state, and the operations from step A1 to step A2 are repeated again to complete the state reset.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] 1. The present invention is provided with a traveling base, a gantry, a grinding power assembly, a main grinding roller, a follow-up adjustment assembly and a side grinding roller. The grinding power assembly cooperates with the main grinding roller to form a transverse grinding part to grind the top of the box beam. The grinding power assembly and the follow-up adjustment assembly cooperate with the side grinding roller to form an adjustable inclined grinding part. The transverse grinding part grinds the upper surface of the box beam inner mold. The adjustable inclined grinding part grinds the box beam inner mold. At the same time, the adjustable inclined grinding part is adaptively adjusted with the change of the surface inclination of the box beam inner mold, thereby avoiding the problem that one end of the side grinding roller is excessively worn and the other end of the grinding roller has a poor grinding effect.

[0036] 2. The present invention provides a transmission assembly, including an outer transmission rod and an inner transmission rod. After the angle and height of the follow-up adjustment assembly are changed, the outer transmission rod and the inner transmission rod can maintain continuous transmission of power by extending vertically, so that the multi-end reducer can always maintain the drive of the follow-up adjustment assembly.

The movable end of the hydraulic rod 211 is connected to the grinding power component 3. The grinding power component 3 is driven by the hydraulic rod 211. Under the drive of the hydraulic rod 211, the grinding power component 3 can be adjusted in height, so that the grinding power component 3 can switch between the two states of grinding operation and operation preparation.

[0050] The main grinding roller 4 is arranged between the two groups of grinding power assemblies 3. The main grinding roller 4 is driven by the grinding power assemblies 3. The grinding power assemblies 3 cooperate with the main grinding roller 4 to form a transverse grinding part.

[0051] There are two sets of follow-up adjustment components 5, which are respectively installed at the middle of the opposite sides of the two sets of traveling bases 1. The side grinding roller 6 is installed between the follow-up adjustment component 5 and the grinding power component 3. The side grinding roller 6 is driven by the grinding power component 3. The grinding power component 3, the follow-up adjustment component 5 and the side grinding roller 6 form an adjustable inclined grinding part.

[0052] The transverse grinding part grinds the upper surface of the box beam inner mold, and the adjustable inclined grinding part grinds the box beam inner mold. Meanwhile, the adjustable inclined grinding part is adaptively adjusted as the surface inclination of the box beam inner mold changes.

[0053] The grinding power assembly 3 includes a guide slide 31, a multi-end reducer 32, a transmission assembly 33 and a servo motor 34;

[0054] The guide slide 31 is fixed to the side of the height adjustment component 21, and a vertical opening penetrating the guide slide 31 and the height adjustment component 21 is provided at the fitting surface of the guide slide 31 and the height adjustment component 21. The multi-end reducer 32 is installed inside the guide slide 31, and a connecting block is formed on the back of the multi-end reducer 32. Both sides of the multi-end reducer 32 are provided with limit blocks for vertical sliding limit, and both sides of the guide slide 31 are provided with limit grooves matched with the limit blocks. The multi-end reducer 32 is nested and connected with the limit grooves of the guide slide 31 through the limit blocks. The multi-end reducer 32 is restricted by the guide slide 31, and the connecting block passes through the vertical opening and is connected to the movable end of the hydraulic rod 211. The main grinding roller 4 The main grinding roller 4 is arranged between the lateral output ends of the two groups of multi-end reducers 32. The main grinding roller 4 is driven by the two groups of multi-end reducers 32. Driven by the hydraulic rod 211, the multi-end reducer 32 can adjust the vertical position inside the guide slide 31, so that the two groups of multi-end reducers 32 synchronously drive the main grinding roller 4 to adjust the up and down position. When the main grinding roller 4 is at the upper part of the guide slide 31 driven by the multi-end reducer 32, the main grinding roller 4 is in the operation preparation state. When the main grinding roller 4 is at the lower part of the guide slide 31 driven by the multi-end reducer 32, the main grinding roller 4 is in the operation state. The main grinding roller 4 switches between the operation preparation state and the operation start state driven by the multi-end reducer 32.

[0055] The servo motor 34 is connected to the input end at the top of the multi-end reducer 32 to provide rotational power for the multi-end reducer 32. The lateral output end of the multi-end reducer 32 drives the main grinding roller 4 to rotate. The rotating main grinding roller 4 can clean the concrete on the surface of the box beam inner mold. The transmission component 33 is connected to the bottom output end of the multi-end reducer 32. The multi-end reducer 32 transmits power to the transmission component 33 from the bottom, so that the transmission component 33 can rotate synchronously.

[0056] The transmission assembly 33 includes a transmission outer rod 331 and a transmission inner rod 332;

[0057] The transmission outer rod 331 is connected to the bottom output end of the multi-end reducer 32, the transmission inner rod 332 is nested and connected to the transmission outer rod 331, and the bottom end of the transmission inner rod 332 is connected to the follow-up adjustment component 5 through a Hooke's hinge. The cooperation of the transmission outer rod 331 and the transmission inner rod 332 transmits the power output from the bottom output end of the multi-end reducer 32 downward to the follow-up adjustment component 5 to drive the follow-up adjustment component 5 to rotate. After the angle and height of the follow-up adjustment component 5 are changed, the transmission outer rod 331 and the transmission inner rod 332 can maintain continuous power transmission by vertical extension, so that the multi-end reducer 32 can always keep driving the follow-up adjustment component 5.

[0058] The follow-up adjustment assembly 5 includes an adjustment slide 51, a sliding connection seat 52, a return spring 53, a connection sleeve 54, a side transmission rod 55 and a guide plate 56;

[0059] The adjusting slide 51 is installed in the middle of one side of the traveling base 1. The adjusting slide 51 is located directly below the guiding slide 31. The sliding connection seat 52 is arranged inside the adjusting slide 51. The sliding connection seat 52 is restricted by the adjusting slide 51. The sliding connection seat 52 can only slide laterally inside the adjusting slide 51.

[0060] The return spring 53 is connected between the side wall of the sliding connection seat 52 and the outer wall of the traveling base 1. Under the elastic force of the return spring 53, the sliding connection seat 52 always has a tendency to move along the adjustment slide 51 toward the traveling base 1.

[0061] The connecting sleeve 54 is connected to the inside of the sliding connecting seat 52 through a rotating shaft, and the connecting sleeve 54 can rotate relative to the sliding connecting seat 52. One end of the side transmission rod 55 is installed inside the connecting sleeve 54 through a bearing, and the side transmission rod 55 can rotate relatively under the support of the connecting sleeve 54. The other end of the side transmission rod 55 is connected to the Hooke hinge at the bottom end of the transmission inner rod 332. During the rotation of the transmission inner rod 332, the transmission inner rod 332 can drive the side transmission rod 55 to rotate through the Hooke hinge. The guide plate 56 is installed on the side The upper end of the transmission rod 55, during the rotation of the side transmission rod 55, the guide plate 56 is driven by the side transmission rod 55 to rotate synchronously, and the rotating guide plate 56 forms an inclined grinding portion, the diameter of the guide plate 56 is smaller than the diameter of the side grinding roller 6, and the guide plate 56 fits with the upper end of the side grinding roller 6. During operation, the side grinding roller 6 contacts the surface of the box beam inner mold, and the guide plate 56 is naturally deformed during the contact with the box beam inner mold, and the guide plate 56 forms a grinding area by means of contact deformation;

[0062] How to use the box beam inner mold grinding equipment:

[0063] The movable end of the hydraulic rod 211 is controlled to move upward, and the movable end of the hydraulic rod 211 moves upward to drive the multi-end reducer 32 to move upward along the guide slide 31, and the two sets of multi-end reducers 32 that move upward drive the main grinding roller 4 to move upward synchronously until the height of the main grinding roller 4 exceeds the height of the top of the box beam inner mold, and the main grinding roller 4 is in an operation preparation state;

[0064] During the upward movement of the multi-end reducer 32, the transmission assembly 33 at the bottom of the multi-end reducer 32 is synchronously moved upward to adjust its own setting position. During the upward movement of the transmission assembly 33, the connection position of the transmission assembly 33 and the upper end of the side transmission rod 55 is synchronously moved upward. As the position of the upper end of the side transmission rod 55 moves upward, under the elastic force of the return spring 53, the sliding connection seat 52 moves horizontally along the adjustment slide 51 toward the traveling base 1. The lower end of the side transmission rod 55 is synchronously adjusted in coordination with the adjustment of the position of the upper end. The side transmission rod 55 is turned from a large inclination angle to a small inclination angle. At this time, the side grinding roller 6 arranged on the side transmission rod 55 is in a ready state for operation.

[0065] The traveling base 1 drives the gantry 2, the grinding power assembly 3, the main grinding roller 4 and the follow-up adjustment assembly 5 to move horizontally until they move to one end of the inner mold of the box beam;

[0066] The movable end of the hydraulic rod 211 is controlled to move downward, and the movable end of the hydraulic rod 211 moves downward to drive the multi-end reducer 32 to move downward along the guide slide 31, and the two groups of multi-end reducers 32 moving downward drive the main grinding roller 4 to move downward synchronously. During the downward movement, the main grinding roller 4 gradually approaches the top of the box beam inner mold, and deforms after the main grinding roller 4 contacts the top of the box beam inner mold. The deformation area of ​​the main grinding roller 4 is the grinding and cleaning area of ​​the top of the box beam inner mold;

[0067] During the downward movement of the multi-end reducer 32, the transmission assembly 33 at the bottom of the multi-end reducer 32 moves downward synchronously to adjust its own setting position. During the downward movement of the transmission assembly 33, the connection position of the transmission assembly 33 and the upper end of the side transmission rod 55 moves downward synchronously. Due to the downward movement of the upper end of the side transmission rod 55, the lower end of the side transmission rod 55 pushes the sliding connection seat 52 to move laterally along the adjustment slideway 51 in the direction away from the traveling base 1 through the connecting sleeve 54. The lower end of the side transmission rod 55 is adjusted synchronously with the adjustment of the position of the upper end. The side transmission rod 55 changes from a small inclination angle to a large inclination angle. At this time, the side grinding roller 6 arranged on the side transmission rod 55 is deformed after contacting with the side wall of the box beam inner mold. The deformation area of ​​the side grinding roller 6 is the grinding and cleaning area of ​​the side wall of the box beam inner mold. At the same time, the guide plate 56 at the upper end of the side transmission rod 55 contacts the side wall of the box beam as the inclination angle of the side transmission rod 55 changes.

[0068] The servo motor 34 is controlled to rotate by an external switch, and the servo motor 34 drives the multi-end reducer 32 to work. The two sets of multi-end reducers 32 cooperate to drive the main grinding roller 4 to rotate, and the rotating main grinding roller 4 grinds the top of the box beam inner mold;

[0069] The two sets of multi-end reducers 32 cooperate to drive the transmission assembly 33 to rotate, and the transmission assembly 33 synchronously drives the side transmission rod 55 to rotate through the Hooke hinge, and the side grinding roller 6 installed outside the side transmission rod 55 grinds the side wall of the box beam inner mold;

[0070] The traveling base 1 moves at a constant speed, and the moving traveling base 1 drives the grinding power assembly 3, the main grinding roller 4, the follow-up adjustment assembly 5 and the side grinding roller 6 to move horizontally from one end of the box beam inner mold to the other end of the box beam inner mold through the gantry 2;

[0071] During the transverse movement of the grinding power assembly 3 and the follow-up adjustment assembly 5, the guide plate 56 maintains contact with the box beam inner mold. During the movement from the end of the box beam inner mold to the middle of the box beam inner mold, due to the gradual increase in the diameter of the box beam, the guide plate 56 can keep the side transmission rod 55 at a fixed distance from the side wall of the box beam inner mold by contact during the transverse movement. During this process, the upper end of the side transmission rod 55 is pushed by the guide plate 56, and the upper end of the side transmission rod 55 moves downward. The transmission inner rod 332 cooperates with the downward movement of the upper end of the side transmission rod 55 and moves downward along the transmission outer rod 331 to maintain normal power transmission. The lower end of the side transmission rod 55 further pushes the sliding connection seat 52 to move transversely along the adjustment slide 51 through the connecting sleeve 54, and the return spring 53 continues to extend and tighten under the pull of the sliding connection seat 52.

[0072] After the guide plate 56 contacts the middle of the side wall of the inner mold of the box beam, the inclination angle of the side transmission rod 55 is fixed, and the side grinding roller 6 installed outside the side transmission rod 55 is kept at a fixed working angle;

[0073] Similarly, after the guide plate 56 contacts the other end of the box beam inner mold side wall, the inclination angle of the side transmission rod 55 is gradually restored until it returns to the initial working preparation state, and the operations from step A1 to step A2 are repeated again to complete the state reset.

[0074] The above description is only a preferred embodiment of the present invention, which is only illustrative and not restrictive of the present invention. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims of the present invention, but all of them will fall within the scope of protection of the present invention.

8. The method for using the box beam inner mold grinding device according to claim 7, characterized in that: The following steps are included: The step A comprises: Step A1, control the movable end of the hydraulic rod to move upward, the movable end of the hydraulic rod moves upward to drive the multi-end reducer to move upward along the guide slideway, and the two sets of multi-end reducers that move upward drive the main grinding roller to move upward synchronously until the height of the main grinding roller exceeds the height of the top of the box beam inner mold, at which time the main grinding roller is in an operation ready state; Step A2, during the upward movement of the multi-end reducer, the transmission assembly at the bottom of the multi-end reducer synchronously moves upward to adjust its own setting position. During the upward movement of the transmission assembly, the connection position of the transmission assembly and the upper end of the side transmission rod synchronously moves upward. Due to the upward movement of the upper end of the side transmission rod, under the elastic force of the return spring, the sliding connection seat moves horizontally along the adjustment slideway toward the traveling base. The lower end of the side transmission rod is synchronously adjusted in coordination with the adjustment of the position of the upper end. The side transmission rod is turned from a large inclination angle to a small inclination angle. At this time, the side grinding roller arranged on the side transmission rod is in a ready state for operation. Step A3, the traveling base drives the gantry, the grinding power assembly, the main grinding roller and the follow-up adjustment assembly to move horizontally until they move to one end of the box beam inner mold; The step B comprises: Step B1, control the movable end of the hydraulic rod to move downward, the movable end of the hydraulic rod moves downward to drive the multi-end reducer to move downward along the guide slideway, and the two sets of multi-end reducers moving downward drive the main grinding rollers to move downward synchronously. During the downward movement, the main grinding rollers gradually approach the top of the box beam inner mold, and deform after the main grinding rollers contact the top of the box beam inner mold. The deformation area of ​​the main grinding rollers is the grinding and cleaning area of ​​the top of the box beam inner mold; Step B2, during the downward movement of the multi-end reducer, the transmission assembly at the bottom of the multi-end reducer synchronously moves downward to adjust its own setting position. During the downward movement of the transmission assembly, the connection position of the transmission assembly and the upper end of the side transmission rod synchronously moves downward. Due to the downward movement of the upper end of the side transmission rod, the lower end of the side transmission rod pushes the sliding connection seat through the connecting sleeve to move laterally along the adjustment slideway in the direction away from the traveling base. The lower end of the side transmission rod is synchronously adjusted in coordination with the adjustment of the position of the upper end. The side transmission rod is turned from a small inclination angle to a large inclination angle. At this time, the side grinding roller arranged on the side transmission rod is deformed after contacting with the side wall of the box beam inner mold. The deformation area of ​​the side grinding roller is the grinding and cleaning area of ​​the side wall of the box beam inner mold. At the same time, the guide plate at the upper end of the side transmission rod contacts the side wall of the box beam as the inclination angle of the side transmission rod changes; The step C comprises: Step C1, controlling the rotation of the servo motor through an external switch, the servo motor drives the multi-end reducer to work, and the two sets of multi-end reducers cooperate to drive the main grinding roller to rotate, and the rotating main grinding roller grinds the top of the box beam inner mold; Step C2, two sets of multi-end reducers cooperate to drive the transmission assembly to rotate, the transmission assembly synchronously drives the side transmission rod to rotate through the Hooke hinge, and the side grinding roller installed outside the side transmission rod grinds the side wall of the box beam inner mold; Step C3, the traveling base moves at a constant speed, and the moving traveling base drives the grinding power assembly, the main grinding roller, the follow-up adjustment assembly and the side grinding roller to move horizontally from one end of the box beam inner mold to the other end of the box beam inner mold through the gantry; Step C4, during the lateral movement of the grinding power component and the follow-up adjustment component, the guide plate maintains contact with the box beam inner mold. During the movement from the end of the box beam inner mold to the middle of the box beam inner mold, due to the gradual increase in the diameter of the box beam, the guide plate can keep the side transmission rod at a fixed distance from the side wall of the box beam inner mold by contact during the lateral movement. During this process, the upper end of the side transmission rod is pushed by the guide plate, and the upper end of the side transmission rod moves downward. The transmission inner rod cooperates with the downward movement of the upper end of the side transmission rod and moves downward along the transmission outer rod to maintain normal power transmission. The lower end of the side transmission rod further pushes the sliding connection seat to move horizontally along the adjustment slide through the connecting sleeve, and the return spring continues to extend and tighten under the pull of the sliding connection seat. Step C5, after the guide plate contacts the middle of the side wall of the box beam inner mold, the inclination angle of the side transmission rod is fixed, and the side grinding roller installed outside the side transmission rod is kept at a fixed working angle; Step C6, similarly, after the guide plate contacts the other end of the box beam inner mold side wall, the inclination angle of the side transmission rod is gradually restored until it returns to the initial working preparation state, and the operations from step A1 to step A2 are repeated again to complete the state reset.
