Description

Technical Field

[0001] This invention belongs to the field of transfer equipment technology, specifically a transfer device for subway construction tools and its usage method. Background Technology

[0002] A subway is a type of urban rail transit system. It refers to a high-speed, high-capacity, electrically powered rail transit system built in cities. Trains run on fully enclosed tracks. Lines located in the city center are generally located in underground tunnels, while lines outside the city center are generally located on elevated bridges or at ground level.

[0003] However, in the existing technology, the existing transfer equipment can only move along the initial track direction and cannot replace the track at any position according to the actual use needs. As a result, when transferring items between multiple tracks, a lot of existing transfer equipment needs to be used simultaneously, which can easily cause the occupation of many tracks and make it inconvenient for the simultaneous use of other construction equipment. At the same time, the existing transfer equipment cannot easily adjust the direction of movement of the items to be transferred according to the actual use situation during the actual transfer process, resulting in poor actual use effect of the existing transfer equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a subway construction tool transfer device and its usage method that can adjust its own track according to actual usage to avoid occupying too much track, and can conveniently adjust the orientation of the items to be transferred according to the direction to be transferred, thereby improving the actual transfer efficiency.

[0005] The technical solution adopted by this invention is as follows: A tool transfer device for subway construction, comprising: a support mechanism, the support mechanism including a base and support components; two mounting shafts penetrating each of the outer surfaces of both sides of the base; a support frame sleeved on the outer surface of each mounting shaft; a movable wheel rotatably connected to one side of the outer surface of each support frame; a drive motor fixedly connected to the other side of the outer surface of each support frame; the output end of each drive motor and the corresponding movable wheel's outer surface fixedly connected; support frames fixedly connected to the other two outer surfaces of the base; a limiting plate embedded inside each support frame; multiple limiting openings equidistantly opened on the top of each limiting plate; and ball bearings slidably embedded inside each limiting opening; the support components are disposed on the base and four support frames; and

[0006] The moving mechanism includes a carrier plate, which is fixedly connected to the top of the base. Two frames are rotatably connected to the top of the carrier plate. Multiple steering rollers are equidistantly connected to the inner walls on both sides of each frame. A linkage gear ring is sleeved on the outer surface of each frame.

[0007] The base has two mounting plates fixedly connected to its top, and an adjusting rod is rotatably connected between the two mounting plates and their opposite outer surfaces. A linkage bevel gear is sleeved on the outer surface of the adjusting rod.

[0008] The base is rotatably connected to a connecting gear at its top, and the connecting gear is also fitted with a connecting bevel gear, with the two connecting bevel gears meshing.

[0009] The base is fixedly connected to a positioning cylinder at its top, and a positioning block is fixedly connected to the output end of the positioning cylinder.

[0010] The base has two adjustable motors fixedly connected to its top, and connecting shafts are rotatably connected to the outer surfaces of both sides of the base. Each connecting shaft has a first bevel gear fitted on its outer surface near its two ends.

[0011] The base has two rotatable worm gears on both outer surfaces. Each worm gear has a second bevel gear on its outer surface. Each second bevel gear meshes with a corresponding first bevel gear. One end of each worm gear is fixedly connected to the output end of the corresponding regulating motor.

[0012] Each of the mounting shafts has a connecting worm gear fitted on its outer surface, and each connecting worm gear meshes with a corresponding connecting worm. Each of the support frames has a mounting groove on its top.

[0013] The supporting component includes four first supporting cylinders and four second supporting cylinders. The four first supporting cylinders are fixedly connected to the corresponding mounting slots. Each first supporting cylinder has a side wheel fixedly connected to its output end. The four second supporting cylinders are divided into two groups. The two groups of second supporting cylinders are fixedly connected to the outer surfaces of the other two sides of the base. Each second supporting cylinder has a support wheel fixedly connected to its output end.

[0014] The two connecting gear rings and connecting gears are meshed, and the top of the carrier plate has a movable opening through which the positioning block slides.

[0015] A method for using a tool transfer device for subway construction includes the following steps:

[0016] S1. Item Transfer: The equipment is placed on the track body via the moving wheels. The drive motor is then started to provide the power required for the moving wheels to rotate, allowing the equipment to move to the desired position. By rotating the adjusting rod, the rotating adjusting rod, in conjunction with the connecting bevel gear, drives the connecting gear to rotate. This, in turn, drives the two carrier frames to rotate, causing the internal steering rollers of the two carrier frames to be in a non-coordinated and non-parallel state. The item to be transferred is then placed on the carrier plate and the top of the steering rollers, ensuring that the item is placed stably. At the same time, the positioning cylinder is started to press the positioning block against the bottom of the item to be transferred, further restricting the position of the item.

[0017] S2. Track Changing Transfer: After the items to be transferred are moved to the designated construction location, the adjustment motor is activated according to the actual required placement position. This, in conjunction with the first and second bevel gears and the connecting shaft, synchronously drives the corresponding connecting worm gear to rotate. The connecting worm gear, in turn, rotates the connecting worm wheel to adjust the operating angle of the support frame, gradually leveling it. At this point, supported by the support wheels, the side wheels are perpendicular to the track body. The existing metal strip is then placed on the track body below the two corresponding side wheels. The first support wheel is then activated. The hydraulic cylinder allows the side wheel to fully contact the top of the existing metal strip. Then, by controlling the activation of the second support hydraulic cylinder, the support wheel can be disengaged from the support of the track body. This allows the equipment to remain completely on top of the existing metal strip via the side wheel, thus facilitating the movement of the equipment to the adjacent track body. Then, by controlling the activation of the second support hydraulic cylinder in reverse, the support wheel is brought back into contact with the track body. The first support hydraulic cylinder is then activated in reverse to separate the side wheel from the existing metal strip. This, in turn, activates the adjusting motor in reverse to ensure that the moving wheel fully contacts the track body, thus facilitating the track changing process of the equipment.

[0018] S3. Reversible Transfer: After the final track change is completed, the rotating adjustment rod allows the internal steering rollers of the carrier frame to be placed parallel according to actual usage requirements. This facilitates the removal of the items to be transferred from the top of the carrier plate and the carrier frame, enabling the equipment to transport the items to be transferred in different transfer directions according to actual usage requirements. At the same time, when the support wheels support the equipment, the control and start adjustment motor can be activated to allow the support frame to rotate away from the track body, so that the top of the moving wheels can be flush with the bottom of the items to be transferred. This allows the rotating moving wheels to assist in supporting the same-direction transfer of the items to be transferred.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] (1) In this invention, when in use, the device is placed on the track body by the moving wheels, and then the drive motor is started by control so that the drive motor can provide the power required for the rotation of the moving wheels, thereby enabling the device to move to the working position. By rotating the adjustment rod, the rotating adjustment rod, together with the connecting bevel gear, drives the connecting gear to rotate, thereby enabling the connecting gear to drive the two carrier frames to rotate, so that the internal turning rollers of the two carrier frames are in a non-coordinated and non-parallel state. Then, the item to be transferred is placed on the carrier plate and the top of the turning roller, so that the item to be transferred can be placed stably. At the same time, the positioning cylinder is started by control so that the positioning block can press against the bottom of the item to be transferred, further restricting the position of the item to be transferred, thereby enabling the device to stably transfer the item to the designated construction position, so that the device can efficiently realize its intended function.

[0021] (2) In this invention, after the items to be transferred are moved to the designated construction location, the adjustment motor is started and controlled according to the actual required placement position. The adjustment motor, together with the first bevel gear, the second bevel gear, and the connecting shaft, can synchronously drive the corresponding connecting worm gear to rotate. This allows the connecting worm gear and the connecting worm wheel to rotate and adjust the use angle of the support frame, gradually making the use angle of the support frame horizontal. At this time, with the support of the support wheels, the side wheels can be perpendicular to the top of the track body. Then, the existing metal strip is placed on the track body below the corresponding two side wheels. Then, the first support cylinder is started and controlled to make the side wheels fully fit the top of the existing metal strip. Finally, the control is activated and controlled to adjust the use angle of the support frame. Activating the second support cylinder allows the support wheel to detach from the track body, enabling the equipment to stop completely on top of the existing metal strip via the side wheel. This allows the equipment to be easily pushed onto the adjacent track body. Then, by reversing the control, the second support cylinder is activated, allowing the support wheel to re-engage with the track body. The first support cylinder is then activated in reverse, separating the side wheel from the existing metal strip. This, in turn, reverses the operation of the adjustment motor, ensuring the moving wheel fully engages with the track body. This facilitates track changing, avoids excessive use of the track body, improves the actual performance of the equipment, and allows for simultaneous use of other construction equipment, thus increasing overall construction efficiency.

[0022] (3) In this invention, after the final track change is completed, the rotating adjustment rod is used to make the internal steering rollers of the carrier frame parallel to the actual use requirements, so as to facilitate the removal of the items to be transferred from the top of the carrier plate and the carrier frame. This allows the equipment to transport the items to be transferred in different transfer directions according to the actual use requirements. At the same time, when the support wheel supports the equipment, the starting adjustment motor can be controlled to make the support frame rotate away from the track body, so that the top of the moving wheel can be flush with the bottom of the items to be transferred. This allows the rotating moving wheel to assist in supporting the transfer of the items to be transferred in the same direction, so that the equipment can efficiently perform its intended functions.

[0034] Please see Figure 6The moving mechanism 2 includes a carrier plate 201, which is fixedly connected to the top of the base 101. Two carrier frames 202 are rotatably connected to the top of the carrier plate 201. Multiple steering rollers 203 are rotatably connected at equal distances between the inner walls of each carrier frame 202 on both sides. A linkage gear ring 204 is sleeved on the outer surface of each carrier frame 202. The two linkage gear rings 204 and the linkage gear 104 are meshed. A moving opening is opened at the top of the carrier plate 201, and the positioning block 106 slides through the moving opening.

[0035] The following is a detailed description of the method of using a subway construction tool transfer device provided in an embodiment of the present invention, which includes the following steps:

[0036] Step 1, Item Transfer: The equipment is placed on the track body 3 via the moving wheels 119. Then, the drive motor 120 is started to provide the power required for the rotation of the moving wheels 119, thereby enabling the equipment to move to the working position. By rotating the adjusting rod 102, the rotating adjusting rod 102, in conjunction with the connecting bevel gear 103, drives the connecting gear 104 to rotate. In turn, the connecting gear 104, in conjunction with the connecting gear ring 204, drives the two carrier frames 202 to rotate, so that the internal turning rollers 203 of the two carrier frames 202 are in a non-coordinated and non-parallel state. Then, the item to be transferred is placed on the carrier plate 201 and the top of the turning rollers 203, so that the item to be transferred can be placed stably. At the same time, the positioning cylinder 105 is started to press the positioning block 106 against the bottom of the item to be transferred, further restricting the position of the item to be transferred. This allows the equipment to stably transfer the item to the designated construction position, enabling the equipment to efficiently perform its intended functions.

[0037] Step Two, Track Changing and Transfer: After the items to be transferred are moved to the designated construction location, the adjusting motor 110 is activated according to the actual required placement position. The adjusting motor 110, in conjunction with the first bevel gear 112, the second bevel gear, and the connecting shaft 111, synchronously drives the corresponding connecting worm gear 113 to rotate. This, in turn, allows the connecting worm gear 113, in conjunction with the connecting worm wheel 115, to rotate and adjust the operating angle of the support frame 116, gradually leveling it. At this point, supported by the support wheel 122, the side wheels 118 are perpendicular to the top of the track body 3. The existing metal strip is then placed on the track body 3 below the corresponding two side wheels 118. Finally, the first support cylinder 117 is activated, ensuring that the side wheels 118 fully contact the top of the existing metal strip. Then, by controlling the activation of the second support cylinder 121, the support wheel 122 can be disengaged from the support of the track body 3, allowing the equipment to be completely stopped on the top of the existing metal strip via the side wheel 118. This allows the equipment to be easily pushed to the top of the adjacent track body 3. Then, by controlling the activation of the second support cylinder 121 in reverse, the support wheel 122 is brought back into contact with the track body 3. The first support cylinder 117 is then activated in reverse, causing the side wheel 118 to separate from the existing metal strip. Then, the adjusting motor 110 is activated in reverse, allowing the moving wheel 119 to fully contact the track body 3. This allows for easy track changing of the equipment, avoids excessive occupation of the track body 3, improves the actual use effect of the equipment, and facilitates the simultaneous use of other construction equipment, thereby improving the overall construction efficiency.

[0038] Step 3, Reversible Transfer: After the final track change is completed, by rotating the adjusting rod 102, the internal steering rollers 203 of the carrier frame 202 can be placed parallel according to actual usage requirements, thus facilitating the removal of the items to be transferred from the top of the carrier plate 201 and the carrier frame 202. This allows the equipment to transport the items to be transferred in different transfer directions according to actual usage requirements. At the same time, when the support wheel 122 supports the equipment, the adjusting motor 110 can be started by controlling the start of the motor, so that the support frame 116 can rotate away from the track body 3, and the top of the moving wheel 119 can be flush with the bottom of the items to be transferred. This allows the rotating moving wheel 119 to assist in supporting the same-direction transfer of the items to be transferred, enabling the equipment to efficiently perform its intended functions.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

9. A method of using a tool transfer device for subway construction, characterized in that, The method of applying the subway construction tool transfer device as described in claim 8 includes the following steps: S1. Item transfer: The equipment is placed on the track body (3) by the moving wheels (119), and then the drive motor (120) is started by control, so that the drive motor (120) can provide the power required for the moving wheels (119) to rotate, thereby enabling the equipment to move to the use position. By rotating the adjusting rod (102), the rotating adjusting rod (102) cooperates with the connecting bevel gear (103) to drive the connecting gear (104) to rotate, thereby enabling the connecting gear (104) to cooperate with the connecting gear ring (204) to drive the two carrier frames (202) to rotate, so that the internal turning rollers (203) of the two carrier frames (202) are in a non-coordinated and non-parallel state. Then the item to be transferred is placed on the top of the carrier plate (201) and the turning roller (203), so that the item to be transferred can be placed stably. At the same time, the positioning cylinder (105) is started by control, so that the positioning block (106) can press against the bottom of the item to be transferred, further restricting the position of the item to be transferred. S2, Track Changing Transfer: After the items to be transferred are moved to the designated construction location, the adjustment motor (110) is started by controlling the actual placement position. The adjustment motor (110) works with the first bevel gear (112), the second bevel gear, and the connecting shaft (111) to synchronously drive the corresponding connecting worm (113) to rotate. The connecting worm (113) works with the connecting worm wheel (115) to rotate and adjust the operating angle of the support frame (116). The operating angle of the support frame (116) gradually becomes horizontal. At this time, under the support of the support wheel (122), the side wheel (118) can be perpendicular to the track body (3). The existing metal strip is then placed on the track body (3) below the two corresponding side wheels (118). Then, the first support is started by controlling the adjustment motor (110) to rotate. The hydraulic cylinder (117) enables the side wheel (118) to fully fit against the top of the existing metal strip. Then, by controlling the activation of the second support hydraulic cylinder (121), the support wheel (122) is able to detach from the support of the track body (3), allowing the equipment to remain completely on the top of the existing metal strip via the side wheel (118). This allows the equipment to be easily pushed to the top of the adjacent track body (3). Then, by controlling the activation of the second support hydraulic cylinder (121) in the reverse direction, the support wheel (122) is brought into contact with the track body (3) again. The first support hydraulic cylinder (117) is then activated in the reverse direction, causing the side wheel (118) to separate from the existing metal strip. Then, the adjusting motor (110) is activated in the reverse direction, allowing the moving wheel (119) to fully fit against the track body (3), thus enabling the equipment to easily change tracks. S3, Reversed Transfer: After the final track change is completed, by rotating the adjusting rod (102), the internal turning roller (203) of the carrier frame (202) can be placed in parallel according to the actual use requirements, so as to facilitate the removal of the items to be transferred from the top of the carrier plate (201) and the carrier frame (202), so that the equipment can transport the items to be transferred in different transfer directions according to the actual use requirements. At the same time, when the support wheel (122) supports the equipment, the starting adjusting motor (110) can be controlled to make the support frame (116) rotate away from the track body (3), so that the top of the moving wheel (119) can be flush with the bottom of the items to be transferred, so that the rotating moving wheel (119) can assist in supporting the transfer of the items to be transferred in the same direction.
