Description

Technical field

The present invention relates to a field of joints, in particular to a construction of a sliding slot.

State of the art

Currently known pavement structures for sliding cracks. One of the coating structures is described in Chinese Patent Application WO2015090045 (A) CN.

Multiple flexible joint connections, such as those between bogies, tractor and trailer, and other flexible attachments, often require a flexible joint to be covered to prevent production damage or injury to service personnel due to objects falling into the joint. . Some of the devices used are awkward for adjustment and installation. This complicates maintenance and repair work. Although some units are easy to dismantle, overall retention power is insufficient and stability is poor.

The essence of the invention

It is an object of the present invention to provide a coating structure for a movable slit capable of overcoming the above defects.

According to the present invention, a coating structure for movable crevices is used to cover movable crevices between the first element and the second element, which can be flexibly joined. The coating structure comprises an elastic material member and a block actuator elastic member that can move horizontally within the cavity of the elastic material member. The block actuator elastic member includes an elastic, top-pressing power transmission member, two wedge-shaped gear members fixedly mounted on either side of the elastic, top-pressing power transmission member, and an internal threaded coupling, mounted rigidly on the top, the central axis of the compressive force transmission member through the peripheral fixed gears. The front and rear of the elastic member of the drive unit drive are symmetrically mounted hinged plates. The hinged plates have a central rigid plate rigidly connected to the respective end of the internal threaded sleeve and a pinion and a pull plate hinged to each side of the middle rigid plate. The outer end of the gear pushing and pulling plates is pivotally connected to the adjacent end of one of the two wedge-shaped gear members, respectively. Any of the two wedge-shaped gear members includes a plurality of wedge-shaped gear members delimited by a slope portion and a plane portion parallel to the central axis. The slip channel is mounted on the inner surface of both the front wall and the rear wall of the elastic material member. The ball mounting groove is located in the slip channel. The ball is mounted in a ball mounting groove. The slip channel is equipped with two connecting slides which can be extended horizontally and retracted. In addition, the two support sliders rest on the ball. The two support sliders are pulled toward each other by shrinkage of the elastomer, and a multiple number of wheels is mounted on the inner surface of each joint slider. Each repeat wheel corresponds to one of several wedge-shaped gear elements one after the other. The internal threaded sleeve and the adjusting screw rod are aligned with the screw threads. The adjusting bolt rod is rotated in the circumferential direction and is fixed axially on the front stationary plate mounted on the front sidewall and the rear stationary plate located on the rear sidewall. The drive motor is mounted on the rear stationary plate. The drive motor is functionally connected to the end of the adjusting bolt rod. The electronic control unit is also mounted on the rear fixed panel. An electronic control device is used to control the forward and reverse rotation of the drive motor. Thus, when the drive motor causes the adjusting bolt rod to rotate so that the block elastic member of the drive unit moves horizontally. In such a way that the two connecting slides can be extended and retracted horizontally so that any of the connecting slides can be pushed into the first supporting groove of the first element and into the second supporting groove of the second element. In this way, the pavement structure can be flexibly coated between the first member and the second member and cover a movable gap.

Because the wedge-shaped teeth fit with a multiple of the wheel slide cavity of the present invention, the thrust may be evenly adjusted in the longitudinal direction of the bearing cushion to lock the cushion slide into a two-component bearing cavity. During the setting of the elastic, top-pressing force transmission element between the two wedge-shaped gear elements, the extrusion force between the bearing cushions on both sides can be elasticly transmitted when the planes contact the wheels to lock the bearing cushion. In this way, the coating device has a stable voltage and the difference between the left and right elements is allowed. Through the setting of the reciprocally pivotable plate and the pinion pulling plate, elastic deformation of the elastic top-pressing transmission component is allowed, and the wedge-shaped pinion element can be reliably pushed and pulled together as the bolt rod pushes and pulls the threaded sleeve. This guarantees synchronous movement of the wedge-shaped gear member so that the movement of the bearing cushion can be reliably controlled. Through the setting of the coupling with peripheral gears, the pulling force can be synchronously transmitted to the elastic top-pressing force transfer member, and the pivoting member may be fixed so that the entire structure improves the pulling properties. With its robust and reliable design, the device is easy to use and can effectively solve the problem of existing technologies.

The support block drive elastic member (71) is provided with symmetrically mounted hinged plates (712, 714) front and rear. The pivotally interconnected plates (712, 714) have a central rigid plate (21) rigidly connected to the respective end of the internal threaded sleeve (713) and a pinion and pull plate (19, 20) hinged to each of the central rigid plates (21). ) sides. The outer end of the gear pushing and pulling plates (19, 20) is pivotally connected to the respective end of one of the two wedge-shaped gear elements (715, 716). Any of the two wedge-shaped gear members (715, 716) includes a plurality of wedge-shaped gear members delimited by an inclined portion (17) and a plane portion (18) parallel to the central axis. The slip channel is mounted on the inner surface of both sides of the front wall (742) and the rear wall (741) of the resilient material element (74). The ball mounting groove is located in the slip channel. The ball (61) is mounted in the ball mounting groove. The slip channel is provided with two support connection slides (72, 73) which can be extended horizontally and retracted. In addition, the two support sliders (72, 73) rest on the ball (61). The two support sliders (72, 73) are pulled towards each other by shrinkage of the elastomer, and a plurality of wheels (721) are mounted on the inner surface of each joint slider (72, 73). Each repeat wheel (721) corresponds to one of several wedge-shaped gear elements one after the other. The internal threaded sleeve (713) and the adjusting screw rod (730) are aligned with the screw threads. The adjusting bolt rod (730) is pivoted in the circumferential direction and is fixed axially on the front stationary plate (744) mounted on the front sidewall (742) and the rear stationary plate (743) on the rear sidewall (741). The drive motor (731) is mounted on the rear stationary plate (743). The drive motor (731) is functionally connected to the end of the adjusting bolt rod (730). The electronic control unit (733) is also mounted on the rear stationary plate (743). The electronic control unit (733) is used to control the forward and reverse rotation of the drive motor (731). Thus, when the drive motor (731) causes the adjusting bolt rod (730) to rotate so that the block drive actuator elastic member (71) moves horizontally. In such a way that the two connecting slides (72, 73) can be extended and retracted horizontally so that any of the connecting slides (72, 73) can be pushed into the first supporting groove (80) of the first element (8) and into a second support groove (90) for the second element (9). In this way, the pavement structure can be flexibly coated between the first element (8) and the second element (9) and cover a movable gap.

Optionally, the first element (8) and the second element (9) are wheelchairs which are connected in a flexible manner.

The positive effect is that the pivot shaft between the pivotally interconnected plates adopts the structure with the end of the disc transmitting the axial pulling force.

Positive effect is that the number of wedge gear groups on each side and the rolling wheels is 3.

Because the wedge-shaped teeth fit with a multiple of the wheel slide cavity of the present invention, the thrust may be evenly adjusted in the longitudinal direction of the bearing cushion to lock the cushion slide into a two-component bearing cavity. During the setting of the elastic, top-pressing force transfer element between the two wedge-shaped gear elements, the extrusion force between the bearing cushions on both sides can be transmitted elasticly when the planes contact the wheels to lock the bearing cushion. In this way, the coating device has a stable voltage and the difference between the left and right elements is allowed. Through the setting of the reciprocally pivotable plate and the pinion pulling plate, elastic deformation of the elastic top-pressing transmission component is allowed, and the wedge-shaped pinion element can be reliably pushed and pulled together as the bolt rod pushes and pulls the threaded sleeve. This guarantees synchronous movement of the wedge-shaped gear member so that the movement of the bearing cushion can be reliably controlled. Through the setting of the peripheral gears, the pulling force can be transmitted synchronously to the elastic top-pressing force transfer member, and the pivoting member may be rigidly attached so that the entire structure improves the pulling properties.

The scope of protection of the present invention depends on the appended definition. Various changes and modifications to the scope of the invention can be made by those skilled in the art by conventional techniques.
