Description

Technical Field

[0001] The utility model relates to the technical field of pushing equipment, in particular to a walking type pushing device and a pushing system. Background Art

[0002] During the process of bridge construction, prefabricated steel beams need to be moved along the direction of bridge piers to the installation position. The existing three-way pushing equipment can realize the lifting and translation of steel beams. Through reciprocating lifting and translation, the steel beams can move along a straight line or a curve. The existing three-way pushing equipment uses an oil cylinder as the power device of the moving seat. If the moving distance of the moving seat for one-time translation needs to be larger, the length of the telescopic rod of the oil cylinder needs to be longer, resulting in a longer overall size of the oil cylinder, making the overall size and weight of the existing three-way pushing equipment larger. During the transportation or installation process of the three-way pushing equipment, the exposed oil cylinder is easily knocked and damaged. Moreover, when the oil cylinder is in a contracted state, the entire oil cylinder and the moving seat still occupy separate spaces, and the overall size of the three-way pushing equipment is relatively large, especially the length dimension, which is not convenient for transportation. Content of the Utility Model

[0003] The purpose of the utility model is to provide a walking type pushing device and a pushing system that are not easily damaged and are more convenient for transportation in view of the problems existing in the prior art.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A walking type pushing device includes a fixed seat and a moving seat slidably arranged on the fixed seat. The moving seat can slide relative to the fixed seat along a first direction. The device further includes a first telescopic device, a second telescopic device, and a third telescopic device. One end of the first telescopic device is connected to one end of the fixed seat along the first direction. The first telescopic device is used to drive the moving seat to slide along the first direction. The second telescopic device is fixed on the moving seat. The third telescopic device is slidably arranged on the moving seat. The second telescopic device is used to drive the third telescopic device to slide along a second direction. The third telescopic device can telescopically move along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. A first accommodating cavity and a second accommodating cavity are arranged in sequence along the third direction in the moving seat. The other end of the first telescopic device passes through the first accommodating cavity and is connected to the moving seat. The third telescopic device is located in the second accommodating cavity. The total length of the third telescopic device in the contracted state is less than or equal to the depth of the second accommodating cavity.

[0006] Further, the movable seat includes a surrounding plate and a partition plate. An accommodation cavity is formed between the inner side walls of the surrounding plate. The partition plate is located in the accommodation cavity and fixedly connected to the surrounding plate. The first accommodation cavity and the second accommodation cavity are respectively formed between the partition plate and the surrounding plate.

[0007] Further, the third telescopic device is slidably arranged on the partition plate, and a self-lubricating material structure is provided between the partition plate and the third telescopic device.

[0008] Further, a support plate is hinged to the end of the telescopic part of the third telescopic device.

[0009] Further, the fixed seat includes a bottom plate and a vertical plate. The two vertical plates extend along the first direction and are fixed on the bottom plate. A chute is formed between the bottom plate and the two vertical plates, and the movable seat is located in the chute.

[0010] Further, stainless steel material structures are provided on the side walls of the bottom plate and the side walls of the vertical plate located in the chute.

[0011] Further, a self-lubricating material structure is provided between the stainless steel material structure on the bottom plate and the movable seat.

The hydraulic station and the controller are electrically connected. The displacement sensor is communicatively connected to the controller. The hydraulic station and the first telescopic device, the second telescopic device, and the third telescopic device are connected through hydraulic pipelines.

[0015] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows: For the walking type pushing device provided by the present utility model, the first telescopic device passes through the first accommodation cavity on the moving seat and is connected to the moving seat, so that part of the first telescopic device is located in the first accommodation cavity in the contracted state, that is, the first telescopic device and the moving seat partially overlap in the first direction, which can reduce the length dimension of the entire walking type pushing device in the contracted state of the first telescopic device and facilitate transportation. The first accommodation cavity and the fixed seat can also play a role in isolating the first telescopic device, so that the first telescopic device is not likely to interfere with the external structure during transportation or installation, thereby reducing the possibility of bump damage. In addition, the total length of the third telescopic device in the contracted state is less than or equal to the depth of the second accommodation cavity of the moving seat, which can enable the third telescopic device to be completely accommodated in the second accommodation cavity in the contracted state, reduce the height dimension of the entire walking type pushing device in the contracted state of the third telescopic device and facilitate transportation.

Detailed implementation

[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Please refer to Figure 1 , the first direction mentioned in the present utility model is shown as the X direction, the second direction is shown as the Y direction, and the third direction is shown as the Z direction.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3 . A walking type pushing device provided by the present utility model is used to push an object so that the object steps in the required direction, thereby achieving the purpose of moving the object. The object can be a steel beam in a bridge structure.

[0026] The walking type pushing device includes a fixed seat 100 and a movable seat 200 slidably arranged on the fixed seat 100. The movable seat 200 can slide relative to the fixed seat 100 in the first direction. It further includes a first telescopic device 300, a second telescopic device 400 and a third telescopic device 500. One end of the first telescopic device 300 is connected to one end of the fixed seat 100 in the first direction. The first telescopic device 300 is used to drive the movable seat 200 to slide in the first direction. The second telescopic device 400 is fixed on the movable seat 200. The third telescopic device 500 is slidably arranged on the movable seat 200. The second telescopic device 400 is used to drive the third telescopic device 500 to slide in the second direction, that is, the second telescopic device 400 and the third telescopic device 500 can slide in the first direction along with the movable seat 200. The third telescopic device 500 can telescopically move in the third direction. The first direction, the second direction and the third direction are perpendicular to each other, so that the object to be pushed can move in three-dimensional directions. The movable seat 200 is provided with a first accommodating cavity 203 and a second accommodating cavity 204 arranged in sequence in the third direction. The other end of the first telescopic device 300 passes through the first accommodating cavity 203 and is connected to the movable seat 200. The third telescopic device 500 is located in the second accommodating cavity 204. The total length of the third telescopic device 500 in the contracted state is less than or equal to the depth of the second accommodating cavity 204.

[0027] Wherein, the other end of the first telescopic device 300 passing through the first accommodating cavity 203 may mean that the end of the telescopic part of the first telescopic device 300 passes through the first accommodating cavity 203, or the fixed part of the first telescopic device 300 passes through the first accommodating cavity 203. The telescopic part refers to the part that can extend or shorten relative to the fixed part, such as a piston rod. Passing through the first accommodating cavity 203 may mean that the first telescopic device 300 runs through the entire first accommodating cavity 203 along the first direction. In other words, the first telescopic device 300 enters the first accommodating cavity 203 from the side of the moving seat 200 close to the connection between the first telescopic device 300 and the fixed seat 100, and exits the first accommodating cavity 203 from the other side of the moving seat 200 away from the connection between the first telescopic device 300 and the fixed seat 100. All or part of the first telescopic device 300 is accommodated in the first accommodating cavity 203; and, the other end of the first telescopic device 300 is connected to the other end of the moving seat 200 along the first direction, as Figure 1 and 2 shown, a connection seat 2012 can be arranged on the other side of the moving seat 200 away from the fixed connection of the first telescopic device 300, and the other end of the first telescopic device 300 passing through the first accommodating cavity 203 is connected to the connection seat 2012. The connection seat 2012 directly bears the thrust or pull force output by the first telescopic device 300; the first telescopic device 300 and the fixed seat 100 can be fixedly connected or detachably connected, and the first telescopic device 300 and the moving seat 200 can also be fixedly connected or detachably connected. As a possible example, for the convenience of applying this device in the jacking of an arc bridge, the first telescopic device 300 is connected to the fixed seat 100 and the moving seat 200 in a hinged manner, so that the moving seat 200 has a certain amount of movement relative to the first telescopic device 300 and the fixed seat 100, and can realize the jacking of an arc track.

[0028] For more convenient transportation or installation and to prevent the third telescopic device 500 from interfering with other structures, when the third telescopic device 500 is in a contracted state, it is completely accommodated in the second accommodating cavity 204, that is, the total length of the third telescopic device 500 in the contracted state is less than or equal to the depth of the second accommodating cavity 204. Combining Figure 1 、 Figure 2 and Figure 4 , the depth of the second accommodating cavity 204 refers to the maximum dimension of the second accommodating cavity 204 along the third direction, and the total length of the third telescopic device 500 refers to the external contour dimension of the third telescopic device 500 along the third direction. When the third telescopic device 500 is in a contracted state, it can be visually observed that the third telescopic device 500 does not protrude from the moving seat 200, or rather, the projected area of the third telescopic device 500 on the vertical plane is smaller than the projected area of the moving seat 200 on the vertical plane.

[0029] As a possible implementation mode, taking the pushing of steel beams as an example, when the walking-type pushing device is in use, in the initial position, first, the third telescopic device 500 needs to be extended along the third direction until it contacts the lower surface of the steel beam, and the steel beam is lifted to be separated from the separately arranged support seat, and then the moving seat 200 is pushed by the first telescopic device 300 to drive the third telescopic device 500 to move along the first direction, thereby driving the steel beam on the third telescopic device 500 to move along the first direction. Before or after the third telescopic device 500 contacts the steel beam, the third telescopic device 500 can also be driven by the second telescopic device 400 to move along the second direction, thereby adjusting the position of the third telescopic device 500 relative to the steel beam or driving the steel beam to move in the third direction. After the first telescopic device 300 pushes the steel beam to the specified position, the third telescopic device 500 contracts, so that the third telescopic device 500 is separated from the lower surface of the steel beam, and the first telescopic device 300 contracts to the initial position. By repeating the above steps, the purpose of pushing the steel beam is achieved.

[0030] As a possible implementation, the movable seat 200 may include a panel 201 and a partition 202, a receiving cavity is formed between the inner side walls of the panel 201, the partition 202 is located in the receiving cavity and is fixedly connected to the panel 201, and a first receiving cavity 203 and a second receiving cavity 204 are respectively formed between the partition 202 and the panel 201. The panel 201 and the partition 202 may be steel plates, the partition 202 and the panel 201 are connected by welding, plugging or bonding, and the partition 202 separates the receiving cavity formed between the inner side walls of the panel 201 into the first receiving cavity 203 and the second receiving cavity 204. The third telescopic device 500 can be slidably arranged on the partition 202. In order to reduce the friction resistance when the third telescopic device 500 slides and make the walking-type pushing device more stable during operation, a self-lubricating material structure 700 is provided between the partition 202 and the third telescopic device 500. The self-lubricating material structure 700 can be provided on the partition 202, or on the third telescopic device 500, or on both the third telescopic device 500 and the partition 202. The self-lubricating material can be fluoroplastic, graphite, polytetrafluoroethylene (PTFE), molybdenum disulfide (MoS2), boron nitride (BN), silicon nitride (Si3N4) and engineering plastics such as nylon (PA), polyoxymethylene (POM) or engineering plastic alloy (Mge) and other materials.

[0031] In order to reduce the pressure exerted by the third telescopic device 500 on the pushed object and reduce the possibility of damaging the pushed object, please refer to Figure 1 , Figure 2 and Figure 3, a support plate 501 is hinged to the end of the telescopic part of the third telescopic device 500. Compared with the third telescopic device 500, the contact area between the support plate 501 and the object to be pushed is larger, which can reduce the pressure of the third telescopic device 500 on the object to be pushed. The hinged connection can also enable the support plate 501 to adapt to the surface slope of the object to be pushed, so that the support plate 501 fits more with the surface of the object to be pushed, thus making the jacking process more stable.

[0032] As a possible implementation manner, please refer to Figure 1 , the fixed seat 100 includes a bottom plate 101 and a vertical plate 102. The two vertical plates 102 extend along the first direction and are fixed on the bottom plate 101. A chute is formed between the bottom plate 101 and the two vertical plates 102. The moving seat 200 is located in the chute. The chute can also play a guiding role, enabling the moving seat 200 to slide more precisely along the first direction and improving the movement stability of the moving seat 200.

[0033] As a possible implementation manner, please refer to Figure 1 and Figure 4 , in order to further reduce the friction between the fixed seat 100 and the moving seat 200, stainless steel material structures 103 are provided on the side walls of the bottom plate 101 and the side walls of the vertical plate 102 located in the chute. The stainless steel material is smoother and can be in direct contact with the moving seat 200. A self-lubricating material structure 700 can also be provided between the bottom plate 101 and the moving seat 200. For example, a self-lubricating material can be provided at the part of the moving seat 200 that contacts the stainless steel material structure 103, or a self-lubricating material structure 700 can be provided on the surface of the stainless steel material structure 103, or self-lubricating material structures 700 can be provided on both the stainless steel material structure 103 and the moving seat 200. The self-lubricating material and the stainless steel cooperate to form a sliding pair with less friction; the stainless steel material structure 103 can also be used as a friction consumable. After the stainless steel material is thinned by friction, it can be replaced to avoid the moving seat 200 body or the fixed seat 100 body being damaged by friction.

[0034] As a possible implementation manner, the first telescopic device 300, the second telescopic device 400, and the third telescopic device 500 can all be hydraulic cylinders, or other telescopic power devices such as electric telescopic cylinders or pneumatic cylinders.

[0035] As a possible implementation, in order to facilitate monitoring the telescopic strokes of the first telescopic device 300, the second telescopic device 400, and the third telescopic device 500 and timely adjust the motion state of the object being pushed, displacement sensors 600 can also be used to detect relevant data. The displacement sensors 600 are fixed on the moving seat 200 and are used to detect the telescopic amounts of the first telescopic device 300, the second telescopic device 400, and the third telescopic device 500. The displacement sensors 600 can be wire rope sensors, laser rangefinders, or photoelectric gates. Exemplarily, please refer to Figure 1 and Figure 2 , an installation groove 2011 can be provided on the retaining plate 201, and the displacement sensors 600 can be arranged in the installation groove 2011. The installation groove 2011 can isolate the displacement sensors 600, making it difficult for external structures to directly interfere with the displacement sensors 600 and reducing the possibility of the displacement sensors 600 being damaged by collision with external structures.

[0036] Please refer to Figure 5 , the walking jacking device can also cooperate with other devices to form a jacking system, including the walking jacking device as described above, and further including a hydraulic station and a controller. The hydraulic station and the controller are electrically connected, the displacement sensors 600 are communicatively connected to the controller, and the hydraulic station is connected to the first telescopic device 300, the second telescopic device 400, and the third telescopic device 500 through hydraulic pipelines.

[0037] As a possible implementation manner, when the present pushing system is in use, the controller can control the hydraulic pressure of the hydraulic station output, so as to control the telescopic strokes of the first telescopic device 300, the second telescopic device 400 and the third telescopic device 500, and further control the motion state of the object to be pushed. For example, there can be multiple walking type pushing devices, that is, two or more. Taking the pushing of a steel beam as an example, when multiple walking type pushing devices are evenly arranged along the second direction, the steel beam can move linearly along the first direction by controlling the synchronous telescoping of the first telescopic device 300, or the steel beam can rotate within the plane where the first direction is located by controlling the differential telescoping of the first telescopic device 300; the steel beam can move up and down along the third direction by controlling the synchronous telescoping of the third telescopic device 500, or the steel beam can rotate within the plane where the third direction is located by controlling the differential telescoping of the third telescopic device 500; the second telescopic device 400 can also be used as a deviation correction device. By controlling the telescoping of the second telescopic device 400, the steel beam can be driven to move along the second direction, the position of the steel beam can be adjusted, and the offset amount of the steel beam along the second direction can be compensated; the controller can also obtain the telescopic amounts of the first telescopic device 300, the second telescopic device 400 and the third telescopic device 500 through the displacement sensor 600, and dynamically adjust the telescopic amounts of the corresponding telescopic devices according to the preset pushing program, so that the steel beam generates the preset motion and / or posture. Communication between the displacement sensor 600 and the controller can be carried out through common wired or wireless communication methods such as cables, optical fibers, Bluetooth, WiFi or cellular networks.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
