[0048] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0049] In the description of the present invention, it should be noted that, unless otherwise specified, "plurality" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be construed as limiting the present invention. In addition, the terms "first", "second", "third", etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model depending on the specific circumstances.

[0051] The utility model provides an anchor changing device and an anchor changing machine, which can provide impact torque and synchronous rotation torque. The operator can select the above functions according to actual needs, complete the anchor changing work quickly and with high quality, re-fix the damaged parts, and ensure the operation and installation of the track.

[0052] When removing embedded parts, such as nylon sleeves, from embedded holes, impact torque can be used. This is because the bonding force between the embedded part and the embedded hole is strong during the long connection process of the old fastener system, so a large torque is required to remove the embedded part. When removing nylon embedded parts, try to avoid damaging the connecting threads in the embedded hole.

[0053] When screwing a new embedded part into the embedded hole and fixing a new anchor bolt to the embedded part, synchronous rotation torque and impact torque can be used.

[0054] The anchor changing device and the anchor changing machine of the present invention are described in detail below with reference to the accompanying drawings. It should be noted that the accompanying drawings and embodiments are only used to explain the anchor changing device and the anchor changing machine of the present invention and cannot be understood as limiting the present invention.

[0055] Figure 1 This is a structural diagram of the modified anchor machine according to an embodiment of the present invention. Figure 1 As shown, the anchor changer 200 of the present invention includes an anchor change device 100, a speed reduction device 240, a motor 230, a power supply 220 and a handle 210, wherein the anchor changer 200 is in a vertical state, and the operator holds the handle 210 to perform anchor change operations.

[0056] The power supply 220 and the motor 230 serve as power sources to provide power for the anchor changer 200. The rotating shaft of the motor 230 is connected to the reduction gear 240 to output the speed required for the anchor change operation. The reduction gear 240 transmits power to the anchor changer 100 at a suitable speed and performs the anchor change operation through the working end 260. Among them, the power source can also be a gasoline engine or a diesel engine.

[0057] Since the sleepers are usually cement sleepers or concrete sleepers, and the embedded parts are cast in the sleepers, the lubrication system 190 needs to be set when the anchor machine 200 is used to operate on the sleepers. The anchor machine 200 provided by the utility model is provided with a lubrication system 190, and the lubrication liquid is input into the working area through the lubrication system 190. Figure 1 and Figure 2 The lubricating liquid enters from the A port of the lubricating system 190 and flows out from the B port of the anchoring device 100 to transport the lubricating liquid to the working area.

[0058] The anchor windlass 200 of the present invention is in a vertical state during operation, and the operator operates in a standing position, reducing the number of times of bending over to save physical strength.

[0059] Figure 2 This is a schematic structural diagram of an anchor changing device according to an embodiment of the present utility model. Figure 3 FIG. 1 is a schematic structural diagram of an anchoring device according to an embodiment of the present invention, showing the connection portion within the housing 150; FIG. Figure 2 and Figure 3 As shown, the anchor changing device 100 of the present invention includes an intermittent transmission mechanism 110 , a power output member 120 and a transmission assembly 130 .

[0060] The transmission assembly 130 includes a shell 150, which has an accommodating space inside. The intermittent transmission mechanism 110 is arranged in the accommodating space; a switching ring 160 is provided on the outer periphery of the shell 150. The operator controls the anchor change device 100 to output impact torque or smoothly output synchronous rotation torque by operating the switching ring 160.

[0061] The intermittent transmission mechanism 110 is provided with a torque input portion 111, which is used to be connected to the output end of the reduction gear 240. One end of the intermittent transmission mechanism 110 is provided with a torque output end 112. Power is input through the torque input portion 111 and the torque output end 112 is intermittently driven to rotate. Figure 6 and Figure 7 The intermittent driving rotation of the torque output end 112 and the impact fit structure between the torque output end 112 and one end of the power output member 120 are clearly described.

[0062] Among them, the power output member 120 transmits the impact torque or synchronous rotation torque to the working area through the output shaft 180. When one end of the power output member 120 is intermittently impact-matched with the torque output end 112, the anchor change device 100 outputs the impact torque; when the power output member 120 is connected to the intermittent transmission mechanism 110 through the transmission assembly 130 and rotates synchronously with the torque input part 111, the anchor change device 100 smoothly outputs the synchronous rotation torque.

[0063] In the anchor change device of this embodiment, a transmission assembly 130 is provided to realize switching between outputting impact torque or synchronous rotation torque of the anchor change device 100. Specifically, one end of the transmission assembly 130 is matched with the intermittent transmission mechanism 110 for transmission, and rotates synchronously with the torque input part 111, so that the power of the torque input part 111 can be directly transmitted to the power output part 120 through the transmission assembly 130.

[0064] The other end of the transmission assembly 130 cooperates with the power output member 120 to form a first transmission structure 131, and along the direction of the rotation axis 132 of the torque output end 112, the other end of the transmission assembly 130 can be detachably transmitted and cooperated with the power output member 120 to drive the power output member 120 and the torque output end 112 to rotate synchronously.

[0065] When the other end of the transmission assembly 130 is connected to the power output member 120 and the transmission is engaged, the power output member 120 rotates synchronously with the torque input portion 111 and the torque output end 112 of the intermittent transmission mechanism 110, thereby stably outputting synchronous rotation torque.

[0066] When the other end of the transmission assembly 130 is in a separated state from the power output member 120, one end of the power output member 120 is impact-matched with the torque output end 112 of the intermittent transmission mechanism 110. Specifically, the torque output end 112 of the intermittent transmission mechanism 110 reciprocates along the direction of the rotation axis 132, and at the same time, the torque output end 112 rotates around the rotation axis 132 at a certain speed, so that the torque output end 112 can apply an impact force to one end of the power output member 120 at a specified frequency, and the power output member 120 outputs an impact torque.

[0067] Figure 4 This is a schematic structural diagram of the anchor changing device according to an embodiment of the present utility model, which shows a structural form in which the first transmission structure in the housing is in a separated state; Figure 5 This is a schematic structural diagram of the anchoring device according to an embodiment of the present invention, which shows the structural form of the transmission cooperation of the first transmission structure in the housing; Figure 4 and Figure 5 As shown, the intermittent transmission mechanism 110 is provided with at least one first transmission groove 113, and the first transmission groove 113 is extended along the direction of the rotation axis 132; the transmission assembly 130 is provided with a first transmission member 133, and the first transmission member 133 is provided with at least one first transmission block 136, and at least part of the first transmission block 136 is arranged in the first transmission groove 113; wherein, the first transmission block 136 moves in the first transmission groove 113 along the direction of the rotation axis 132, so that the other end of the transmission assembly 130 and the power output member 120 can be detachably transmitted and matched.

[0068] In the anchor change device of this embodiment, when the first transmission block 136 on the first transmission member 133 moves along the extension direction of the first transmission groove 113 in the direction away from the power output member 120, and the transmission assembly 130 is separated from the power output member 120, the torque output end 112 of the intermittent transmission mechanism 110 applies an impact force to one end of the power output member 120 at a certain frequency, thereby driving the power output member 120 to rotate and output an impact torque; when the first transmission block 136 on the first transmission member 133 moves along the extension direction of the first transmission groove 113 in the direction close to the power output member 120, so that the transmission assembly 130 and the power output member 120 are in transmission coordination, the power output member 120 rotates synchronously with the transmission assembly 130 and the torque input part 111. Under this condition, the anchor change device 100 smoothly outputs the synchronous rotation torque.

[0069] In one embodiment of the present invention, a plurality of first transmission grooves 113 are provided on the intermittent transmission mechanism 110, and the plurality of first transmission grooves 113 are arranged at intervals around the rotation axis 132 on the intermittent transmission mechanism 110; a plurality of first transmission blocks 136 are provided on the first transmission member 133, and each first transmission groove 113 is suitable for accommodating a first transmission block 136.

[0070] In the anchor relocation device of this embodiment, a plurality of first transmission grooves 113 are spaced apart circumferentially around the intermittent transmission mechanism 110, and a plurality of first transmission blocks 136 are spaced apart circumferentially around the first transmission member 133. This creates multiple transmission structures circumferentially between the intermittent transmission mechanism 110 and the first transmission member 133, thereby improving transmission smoothness. The higher the fit precision between the first transmission grooves 113 and the first transmission blocks 136, and the greater the contact area along the rotation axis 132, the smoother the transmission between the intermittent transmission mechanism 110 and the first transmission member 133.

[0071] Figure 7 This is an exploded view of the intermittent transmission mechanism of the anchor changing device according to an embodiment of the present invention. Figure 7 As shown, the intermittent transmission mechanism 110 includes a first drive shaft 114, a rolling body 118, a rotary sleeve 116, and a spring 119, wherein a first groove 115 is provided on the outer circumference of the first drive shaft 114, and a second groove 117 is provided on the inner surface of the rotary sleeve 116. A portion of the rolling body 118 is arranged in the first groove 115, and another portion of the rolling body 118 is arranged in the second groove 117. When the first drive shaft 114 rotates, the rolling body 118 is driven to roll in the first groove 115, and then the rolling body 118 drives the rotary sleeve 116 to rotate through the second groove 117. The rotation trajectory is determined by the extension direction of the first groove 115 and the second groove 117. Figure 7 As shown, the extended shape of the first groove 115 and the second groove 117 is V-shaped. Therefore, during the rotation process, the rotating sleeve 116 reciprocates along the direction of the rotation axis 132 and can quickly return to the initial position under the elastic force of the spring 119; the spring 119 is installed between the first transmission shaft and the rotating sleeve 116 and is in a compressed state to provide elastic force to the rotating sleeve 116.

[0072] Figure 6 The exploded view of the anchoring device of the present invention shows the structure of the transmission assembly 130, the intermittent transmission mechanism 110 and the power output member 120. Figure 6 ,as well as Figure 4 and Figure 5 One of the power output member 120 and the first transmission member 133 is provided with at least one second transmission groove 137, and the other is provided with at least one second transmission block 121, wherein the second transmission block 121 is detachably inserted into the second transmission groove 137 along the direction of the rotation axis 132.

[0073] In the anchor relocation device of this embodiment, a second transmission block 121 is provided on the power output member 120, and a second transmission groove 137 is provided on the first transmission member 133. When the first transmission member 133 moves along the rotation axis 132, the first transmission block 136 and the second transmission groove 137 are engaged or disengaged. Alternatively, the second transmission groove 137 may be provided on the power output member 120, and the second transmission block 121 may be provided on the first transmission member 133.

[0074] The first transmission block 136 on the first transmission member 133 moves along the first transmission groove 113 on the intermittent transmission mechanism 110 to adjust the transmission engagement or separation between the second transmission block 121 and the second transmission groove 137 .

[0075] Figure 8 This is a schematic structural diagram of the housing and the switching ring of the anchor changing device according to an embodiment of the present invention. Figure 8 As shown, in one embodiment of the present invention, the transmission assembly 130 further includes a toggle assembly 140, which is connected to the first transmission member 133 and is capable of driving the first transmission member 133 along the direction of the rotation axis 132 to achieve detachable transmission engagement with the power output member 120. In this embodiment, the anchor repositioning device 100 applies a driving force to the first transmission member 133 via the toggle assembly 140, thereby driving the first transmission member 133 to move along the direction of the rotation axis 132, thereby achieving transmission engagement or separation between the first transmission member 133 and the power output member 120.

[0076] In one embodiment of the present invention, the first transmission member 133 is provided with a receiving cavity 134, and at least a portion of the intermittent transmission mechanism 110 is disposed within the receiving cavity 134. The anchor re-alignment device 100 of this embodiment, by disposing the intermittent transmission mechanism 110 within the receiving cavity 134, can protect the intermittent transmission mechanism 110 from external interference and also ensure that the various components of the intermittent transmission mechanism 110 remain stably connected during transmission, rather than being separated by centrifugal force.

[0077] In one embodiment of the present invention, an annular groove 135 is defined on the outer periphery of first transmission member 133. A toggle assembly 140 includes at least one toggle lever 141, one end of which extends into annular groove 135 to drive first transmission member 133 to move along rotation axis 132. In this embodiment of the anchor repositioning device 100, toggle lever 141 applies a force within annular groove 135, thereby causing first transmission member 133 to move along the rotation axis.

[0078] In one embodiment of the present invention, the transmission assembly 130 further includes a housing 150, which is provided with a drive slot 151. At least a portion of the toggle assembly 140 is disposed within the drive slot 151 and engages with the first transmission member 133. The drive slot 151 has a drive stroke 152 along the direction of the rotation axis 132. In this embodiment of the anchor repositioning device 100, one end of the toggle assembly 140, such as the toggle rod 141 therein, passes through the drive slot 151 of the housing 150 to drive the first transmission member 133. Alternatively, one end of the toggle assembly 140 can be extended into the annular groove 135 of the first transmission member 133. When the toggle assembly 140 moves within the drive slot 151, the one end of the toggle assembly 140 drives the first transmission member 133 to move along the direction of the rotation axis 132.

[0079] It should be noted that the driving stroke 152 of the driving slot 151 in the direction of the rotation axis 132 of the first transmission member 133 should correspond to the matching distance between the second transmission slot 137 and the second transmission block 121 in the direction of the rotation axis 132, that is, when one end of the toggle assembly 140 moves from one end of the driving slot 151 to the other end, one end of the toggle assembly 140 can drive the driving stroke 152 of the first transmission member 133 in the direction of the rotation axis 132, and can enable the transmission between the second transmission block 121 and the second transmission slot 137 to cooperate or separate.

[0080] In one embodiment of the present invention, the transmission assembly 130 further includes a switching ring 160, which is sleeved on the outside of the housing 150 and disposed opposite the annular groove 135 or the drive groove 151. At least one toggle rod 141 is disposed on the switching ring 160. In the anchor resetting device 100 of this embodiment, the switching ring 160 is disposed on the housing 150 and disposed opposite the drive groove 151 and the annular groove 135. Therefore, when the switching ring 160 is actuated, the toggle rod 141 connected to the switching ring 160 is driven to move within the drive groove 151, thereby driving the first transmission member 133 to move along the rotation axis 132 via the annular groove 135.

[0081] In one embodiment of the present invention, the transmission assembly 130 further includes a locking member 170, which is disposed through the switching ring 160. The housing 150 is provided with a stop hole 153, which is disposed opposite one end of the locking member 170. In the anchor resetting device 100 of this embodiment, when one end of the locking member 170 extends into the stop hole 153, the relative position between the switching ring 160 and the housing 150 is fixed. Furthermore, the relative positions between the transmission assembly 130 and the intermittent transmission mechanism 110, and between the transmission assembly 130 and the power output member 120, are relatively stable, thereby enabling the anchor resetting device 100 to continuously output impact torque or synchronous rotation torque.

[0082] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
