[0030] The present invention will be further described in detail below through specific embodiments:

[0031] In embodiments of the present invention, such as Figures 1-6 As shown, the rolling slipper assembly 100 includes: a base 1, a roller 2, a braking structure 3, and a driving structure 4; the roller 2 is rotatably disposed on the base 1 on the rotation axis;

[0032] Braking structure 3 includes a rotating member 301 and a braking member 303. The rotating member 301 is connected to the roller 2, enabling it to rotate in the same direction as the roller 2 along the rotation axis. The rotating member 301 has a ratchet portion 302. The braking member 303 is movably disposed on the base 1 and has a pawl portion 304. The pawl portion 304 cooperates with the ratchet portion 302 to allow the rotating member 301 to follow the roller 2 in a first rotation direction along the rotation axis, and to restrict the rotating member 301 from rotating in a second rotation direction opposite to the first rotation direction, thereby restricting the roller 2 from rotating in the second rotation direction.

[0033] A driving structure 4 is arranged on the base 1 and drives the brake 303 to move along a direction parallel to the rotation axis. The driving structure 4 is forced to move the brake 303 to the rotating member 301 relative to the base 1, so as to maintain the cooperation between the ratchet wheel part 302 and the pawl part 304, or to move the brake 303 away from the rotating member 301, so as to release the cooperation between the ratchet wheel part 302 and the pawl part 304, and the roller 2 and the rotating member 301 can rotate in the first rotation direction or the second rotation direction.

[0034] Specifically, in the embodiment of the present application, the base 1 is the supporting foundation of the whole slide shoe assembly 100, and has an upper surface and a lower surface. The upper surface of the base 1 is used to support a steel structure (for example, a steel structure net rack), and the end thereof can be connected with a hydraulic driving mechanism. The lower surface of the base 1 is provided with a rotatable roller 2. Figure 1 As shown in the figure, the slide shoe assembly 100 is installed in a slide rail, and the hydraulic driving mechanism provides a pushing force and drives the slide shoe assembly 100 to slide relative to the slide rail through the rotation of the roller 2, so that the steel structure can be sent to a designed position. Of course, as shown in the figure, the roller 2 can also be provided in multiple or multiple groups, so as to balance the supporting force and reduce the friction between the base 1 and the slide rail. Figure 2 On the other hand, in order to improve the sliding precision of the base 1 in the slide rail, the upper surface of the base 1 is provided in a bow shape (as shown in the figure). Meanwhile, in order to improve the structural strength of the slide rail, lateral stop blocks are welded on both sides of the slide rail, which can resist the pushing force of the base 1. Figure 3

[0035] The roller 2 is used to replace the original steel plate, which reduces the friction between the whole slide shoe assembly 100 and the slide rail, and a smaller pushing force can be used to drive the slide shoe assembly 100 to move forward, which is convenient for construction. However, when the slide rail is installed on uneven ground, or the slide rail is in a wet or oily place, or the roller 2 is more likely to slide accidentally due to load reasons, etc., the sliding precision of the slide shoe assembly 100 will be affected, and the positioning precision of the steel structure will be low.

[0036] ​To this end, the embodiment is provided with a braking structure 3 capable of locking the roller 2 at its current position after moving to the position and avoiding accidental slipping. Specifically, the braking structure 3 includes a rotating member 301 and a braking member 303, the rotating member 301 is connected with the roller 2 through a connecting shaft, so that the rotating member 301 can rotate synchronously and in the same direction with the roller 2 along the rotation axis of the roller 2, thereby the rotation of the roller 2 can be embodied at the rotating member 301. Further, in order to be able to brake the rotating member 301, the rotating member 301 and the braking member 303 are respectively provided with a ratchet part 302 and a pawl part 304, the engagement of the ratchet part 302 and the pawl part 304 can form a one-way brake, thereby allowing the rotating member 301 to follow the roller 2 to rotate in a first rotation direction along the rotation axis, and limiting the rotating member 301 to rotate in a second rotation direction opposite to the first rotation direction, thereby being able to prevent the roller 2 from rotating in the second rotation direction.

[0037] In this way, when the base 1 is pushed forward by an external force, the roller 2 can rotate in the first rotation direction and drive the rotating member 301 to rotate synchronously; after the shoe assembly 100 stops advancing, the roller 2 also stops rotating under normal circumstances; but if the roller 2 slips accidentally, the roller 2 will have a movement tendency to rotate in the second rotation direction and rotate in the same direction with the rotating member 301, at this time, the rotating member 301 can be prevented from rotating in the second rotation direction under the engagement of the ratchet part 302 and the pawl part 304, thereby being able to limit the roller 2 to rotate in the second rotation direction, realize the braking of the roller 2, and prevent the roller 2 from slipping backward. In the embodiment, the one-way locking of the roller 2 is realized by the cooperation of the ratchet part 302 and the pawl part 304, and the cooperation of the braking mode with the rotation directions of the roller 2 and the rotating member 301, and a reliable rigid one-way locking is provided to ensure that the shoe assembly 100 will not be displaced due to slight disturbance in the static state. In addition, the synchronous and same-direction rotation of the roller 2 and the rotating member 301 is used to realize the purpose of one-way braking by the rotation of the roller 2, compared with the wedge-shaped block inserted into the rear of the roller 2, not only additional operations are required for placement and removal, but also the use is inconvenient and easy to lose, and the wedge-shaped block may not be able to provide sufficient resistance on the slope, which is not suitable for the scene requiring frequent switching between moving and locking states.

[0038] In the embodiment, in order to enable the sliding shoe assembly 100 to slide back and forth so as to accurately reach the designed position, the rotating member 301 and the brake member 303 are connected in a separable manner, and the brake member 303 is movably arranged on the base 1 since the rotating member 301 needs to be connected with the roller 2. Further, in order to maintain the one-way locking of the rotating member 301 and the roller 2, i.e. the engagement of the ratchet portion 302 and the pawl portion 304, the brake member 303 is connected with the driving structure 4, and the driving structure 4 can enable the brake member 303 to move back and forth along the direction parallel to the rotation axis after being subjected to a force, so as to realize the engagement or disengagement of the ratchet portion 302 and the pawl portion 304.

[0039] Specifically, when the driving structure 4 drives the brake member 303 to move to the rotating member 301, the ratchet portion 302 and the pawl portion 304 can form the one-way locking mode after being engaged, and the one-way locking mode can be maintained to avoid the accidental sliding of the pawl portion 304. Conversely, when the driving structure 4 drives the brake member 303 to move away from the rotating member 301, the pawl portion 304 and the ratchet portion 302 are disengaged, and the rotating portion is no longer constrained by the brake member 303 at this time, so that the roller 2 and the rotating portion can rotate in the first rotation direction or the second rotation direction under the action of an external force, so as to finely adjust the position of the sliding shoe assembly 100.

[0040] The embodiment can realize the quick switching of the two modes by driving the driving structure 4 to control the movement of the brake member 303: when the brake member 303 is engaged with the rotating member 301, the roller 2 is only allowed to rotate in the first rotation direction, realizing the one-way locking and preventing the sliding shoe assembly 100 from retreating or sliding; when the brake member 303 moves away from the rotating member 301, the disengagement of the ratchet portion 302 and the pawl portion 304 enables the roller 2 to freely rotate in the first and second rotation directions, meeting the flexible movement requirement. At the same time, once the roller 2 rotates in the second rotation direction, the one-way locking mode will be triggered, and the response speed is faster. Of course, in other embodiments, the brake structure 3 and the driving structure 4 can be increased or decreased according to the number of rollers 2, the load condition and the like, which is not limited herein.

[0041] As shown in the embodiment, the driving structure 4 comprises a sliding block, and the brake member 303 is arranged on the sliding block. Figures 2-5 Specifically, in order to enable the brake member 303 to move linearly in the direction parallel to the rotation axis relative to the rotating member 301, the embodiment is provided with a sliding block arranged on the base 1, and the brake member 303 is connected with the sliding block to realize the back-and-forth sliding, so as to enable the brake member 303 to be engaged or disengaged with the rotating member 301, thereby enabling the roller 2 to form the one-way rotation mode or the two-way rotation mode.

[0042] Further, as shown in the embodiment, the driving structure 4 comprises a driving mechanism, and the sliding block is connected with the driving mechanism.Figures 4-6 As shown in the figure, in an embodiment, the slider has a connecting mounting portion 401 and a sliding portion 402, the brake 303 is arranged on the mounting portion 401, and the sliding portion 402 is slidingly embedded in the base 1. Specifically, on the one hand, in order to facilitate the installation of the brake 303, on the other hand, in order to make the slider slidingly arranged at the base 1; the slider in this embodiment is divided into two parts, i.e. the mounting portion 401 and the sliding portion 402, the mounting portion 401 is used to install the brake 303, and the sliding portion 402 is used to slidingly embed the base 1. As shown in the figure, Figure 6 As shown in the figure, the mounting portion 401 and the sliding portion 402 in this embodiment are arranged perpendicular to each other, and the purpose is to adapt to the position and structure of the base 1 and the roller 2; in other embodiments, they can also be not perpendicular.

[0043] Further, as shown in the figure, Figure 6 As shown in the figure, in an embodiment, the brake 303 and the mounting portion 401 are both provided with protrusions 5, the two protrusions 5 are connected by an elastic member 6, and when the rotating member 301 rotates along the first rotation direction, the elastic member 6 can maintain the cooperation between the ratchet portion 302 and the pawl portion 304. Specifically, in one-way locking, in order to make the ratchet portion 302 and the pawl portion 304 always maintain the cooperation state; in this embodiment, an elastic member 6 is arranged between the brake 303 and the mounting portion 401, and the two ends of the elastic member 6 are fixed at the brake 303 and the mounting portion 401 through the protrusions 5; in addition, in order to cooperate with the rotation of the ratchet portion 302, the pawl portion 304 is arranged to rotate in a small range at the mounting portion 401. In this way, when the rotating member 301 rotates along the first rotation direction, the elastic member 6 will deform and recover, so that the pawl portion 304 always maintains the cooperation with the ratchet portion 302. Preferably, the elastic member 6 is a spring.

[0044] As shown in the figure, Figure 4 , Figure 5 As shown in the figure, in an embodiment, the driving structure 4 further includes a threaded rod 403, the threaded rod 403 is arranged to rotate at the base 1 and penetrates through the sliding portion 402. Specifically, in order to realize the sliding of the slider; in this embodiment, a threaded rod 403 is arranged at the base 1, the slider is sleeved outside the threaded rod 403, and the position of the slider is changed by using external force to rotate the threaded rod 403 in forward and reverse directions, so as to adjust the position of the brake 303 relative to the rotating member 301. The driving source of the threaded rod 403 can be electric or manual.

[0045] As shown in the figure, Figure 4 , Figure 6As shown in the embodiment, the driving structure 4 further comprises a plug 404 which is detachably inserted into the base 1 and penetrates through the mounting portion 401. Specifically, when in one-way locking, in order to improve the connection tightness between the mounting portion 401 and the base 1; the embodiment fixes by setting a plug hole at the corresponding position of the mounting portion 401 and the base 1, and using the plug 404. Or when the sliding portion 402 is manually driven, the plug 404 can be used as a connecting member and a fixing member of the base 1 and the mounting portion 401. Of course, the plug 404 can also be replaced by other members with locking force such as screws.

[0046] As shown in the embodiment, Figure 2 , Figure 3 In an embodiment, the base 1 is provided with a first mounting point 7 for mounting a steel structure and a second mounting point 8 for mounting a hydraulic drive mechanism. The hydraulic drive mechanism can provide a horizontal thrust to the sliding shoe assembly 100.

[0047] As shown in the embodiment, Figure 3 The cross-section of the first mounting point 7 is a cross-shaped structure. The cross-shaped cross-section is composed of two mutually perpendicular steel plates, forming a symmetrical rigid structure. When connected with the steel structure, the force can be more evenly dispersed to the four directions of the cross-shaped structure, avoiding stress concentration at a single contact point. Compared with circular, square and other cross-sections, the cross-shaped cross-section has stronger resistance to complex directional force under the same material consumption, which can improve the stability of the overall connection and reduce the risk of deformation or fracture in long-term use.

[0048] As shown in the embodiment, Figure 2 The rotating member 301 is suspended to avoid blocking the roller 2 in the first or second rotation direction.

[0049] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application, which should be covered by the claims of the present application.
