Preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and the like are used herein for purposes of illustration only and not limitation.

Herein, ordinal words such as "first" and "second" cited in the present utility model are merely identifiers and do not have any other meaning, such as a particular order or the like.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present utility model. It will be apparent that embodiments of the utility model may be practiced without limitation to the specific details that are set forth by those skilled in the art. Preferred embodiments of the present utility model are described in detail below, however, the present utility model may have other embodiments in addition to these detailed descriptions.

The utility model provides a blocking device. The blocking device can be used in a garage. The garage is of at least two-layer structure. At least one floor is provided with a garage for storing vehicles. The garage comprises a lifting channel. The lifting channel is positioned at the car hall. The hoistway extends in a vertical direction from a first level of the garage to a top level of the garage. The garage also comprises a vehicle carrying platform arranged in the lifting channel. The vehicle platform may be for carrying a vehicle. The vehicle platform can move in a vertical direction.

The car hall is provided with an inlet and a passage opening communicated with the lifting passage. The garage hall is provided with a garage hall door for opening or closing the entrance, and an access door for opening or closing the access opening. In this way, vehicles outside the garage may enter the garage through the entrance. Vehicles in the car hall can enter the lifting channel from the car hall through the channel port so as to travel to the car carrying platform, and lift in the lifting channel so as to be stored on different floors. A blocking device may be provided at the entrance for blocking the passage of a vehicle through the entrance when the garage door is unopened.

It will be appreciated that in an embodiment not shown, a blocking device may be provided at the access opening for blocking the vehicle from entering the hoistway when the garage door is not open.

Referring to fig. 1 to 6, the blocking device includes a column 110. The length direction of the column 110 extends in the vertical direction. One end of the upright 110 is fixedly connected to the floor of the car hall. The other end of the upright 110 is fixedly connected to the ceiling of the car hall. The post 110 has a recess 111. The length direction of the groove 111 is parallel to the length direction of the column 110.

As shown in fig. 1 and 2, the number of the columns 110 is two. Along the width direction of the inlet, two columns 110 are disposed at intervals. One end of the latter blocking rod 120 is located in a recess 111 of one of the uprights 110. The other end of the blocking lever 120 is located in the recess 111 of the other upright 110.

Referring to fig. 1 to 4, and fig. 6, the blocking device further includes a blocking lever 120. The end of the blocking lever 120 is disposed in the recess 111. The blocking lever 120 is movable along the length of the column 110 between a blocking position and a passing position. With the blocking lever 120 in the blocking position, the minimum distance between the blocking lever 120 and the upper surface of the floor is smaller than the height dimension of the vehicle to be able to block the passage of the vehicle.

The blocking lever 120 in the passing position may be located above the vehicle to allow the vehicle to pass.

In an embodiment not shown, the blocking lever in the transit position may be located below the upper surface of the floor to allow the vehicle to pass.

The groove 111 can guide the movement of the blocking lever 120 during the movement of the blocking lever 120 in the height direction of the column 110.

As shown in fig. 1 to 4, and fig. 6, the blocking device further includes a drop-off preventing member 130. The drop-out preventing member 130 is connected to the column 110. At least part of the drop-out preventing member 130 is located in the recess 111. A first gap 140 exists between the drop-out prevention member 130 and one inner side 112 of the groove 111. The first space 140 has a size greater than that of the body 121 of the barrier lever 120 in the width direction of the groove 111. Thus, the size of the first space 140 is smaller than the width dimension of the groove 111 in the width direction of the groove 111.

With the blocking lever 120 in the blocking position, the projection of the anti-release member 130 on the first projection plane and the projection of the blocking lever 120 on the first projection plane at least partially coincide. The first projection surface is perpendicular to the width direction of the groove 111. The width direction of the groove 111 is perpendicular to the length direction of the blocking lever 120.

With the blocking lever 120 in the blocking position, the blocking lever 120 is located within the first space 140. Since the dimension of the first space 140 is smaller than the width dimension of the groove 111 in the width direction of the groove 111, the shake range of the blocking lever 120 is small when the vehicle hits the blocking lever 120, and the blocking lever is not easily removed from the groove 111. That is, the provision of the drop-out preventing member 130 can reduce the possibility that the blocking lever 120 is separated from the recess 111 when the vehicle hits the blocking lever 120.

In this embodiment, when a vehicle needs to be blocked (for example, when a garage hall door is not opened or a loading platform does not reach a floor where a hall is located), the blocking lever 120 is located at a blocking position, so that the vehicle can be blocked, and the vehicle is prevented from entering the hall, and may fall into a lifting channel; when vehicles can be allowed to pass (for example, garage hall doors are opened and a loading platform reaches the floor where the hall is located), the vehicles can be allowed to pass by positioning the blocking rod 120 at the passing position; further, in the case where the blocking lever 120 is located at the blocking position, the blocking lever 120 is located in the first interval 140, and the anti-drop member 130 is provided to reduce the possibility that the blocking lever 120 is separated from the groove 111 when the vehicle hits the blocking lever 120.

Preferably, referring to fig. 1, 3 and 6, the blocking lever 120 includes a body 121 and a release preventing portion 122. The body 121 has a rod-like structure. The drop-off prevention portion 122 is located at an end of the body 121. The maximum size of the cross-sectional shape of the drop-off prevention portion 122 (the cross-section is perpendicular to the length direction of the blocking lever 120) is larger than the maximum size of the cross-sectional shape of the body 121 (the cross-section is perpendicular to the length direction of the blocking lever 120). Thus, the end of the blocking lever 120 has a large size and high strength.

As shown in fig. 3, a second space 141 exists between the escape prevention member 130 and the bottom wall of the groove 111 in the length direction of the blocking lever 120. When the blocking lever 120 is in the blocking position, the drop-off preventing portion 122 is located in the second space 141. The projection of the drop-off preventing portion 122 on the second projection surface overlaps with the projection of the drop-off preventing member 130 on the second projection surface. The second projection plane is perpendicular to the length direction of the blocking lever 120. Thereby, the stopper 130 and the stopper 122 act, and the possibility that the blocking lever 120 located at the blocking position is separated from the groove 111 can be further reduced.

Preferably, the body 121 may be rectangular steel. The drop-off preventing portion 122 may be a rectangular tube fitted around the outer circumference of the end of the body 121. Thereby, the processing of the body 121 and the escape prevention part 122 is facilitated.

As shown in fig. 4 and 6, the blocking device includes two drop-off preventing members 130. A third space 142 exists between the two drop-out preventing members 130 in the width direction of the groove 111. The third space 142 has a size greater than that of the body 121 and smaller than that of the escape prevention part 122 in the width direction of the groove 111. With the blocking lever 120 in the blocking position, the body 121 is located within the third space 142. The projection of the drop-off preventing portion 122 on the second projection surface overlaps with the projection of the one drop-off preventing member 130 on the second projection surface. The projection of the drop-off preventing portion 122 on the second projection surface overlaps with the projection of the other drop-off preventing member 130 on the second projection surface. In this way, the two drop-out preventing members 130 and the drop-out preventing portion 122 act together, so that the possibility that the blocking lever 120 in the blocking position is separated from the groove 111 can be further reduced.

Further preferably, as shown in fig. 1, the drop-out preventing member 130 is connected to the inner side surface 112 of the groove 111. Thus, the blocking device is simple in structure.

Preferably, in the case where the blocking lever 120 is located at the blocking position, the blocking lever 120 is located at the vehicle bumper. In this way, the vehicle can be protected.

Preferably, the upright 110 may be H-section steel or channel steel. Thereby facilitating the form selection process of the column 110.

Preferably, one end of the drop preventing member 130 in the length direction of the upright post 110 has an inclined surface 131 such that the size of the first interval 140 at the inclined surface 131 gradually decreases in the direction in which the blocking lever 120 moves from the passing position toward the blocking position. Thus, the inclined surface 131 can guide the body 121 to move into the third space 142 during the movement of the blocking lever 120 from the passing position to the blocking position.

Referring to fig. 1 to 6, the blocking device further includes a driving assembly 150. The driving assembly 150 is connected to the blocking lever 120 for driving the blocking lever 120 to move along the length direction of the column 110. Thereby facilitating the movement of the drive blocking lever 120.

Preferably, the blocking device further comprises a mounting seat 180. The drive assembly 150 includes a drive member 151, a spool 152, a direction-changing wheel 153, and a flexible connection 154. The driving member 151 may be a driving motor. The driving member 151 is connected to the top end of the column 110 through a mount 180. The spool 152 is connected to an output shaft of the driving member 151. A direction-changing wheel 153 is rotatably connected to the top end of the column 110. The direction changing wheels 153 are at least three. Two direction-changing wheels 153 are provided at the top end of the first upright 110. A direction-changing wheel 153 is provided at the top end of the second upright 110.

The flexible connector 154 may be a wire rope. The number of flexible connectors 154 is two. One end of a flexible link 154 is wound around the spool 152 and around a deflector wheel 153 provided at the top end of the first upright 110 and then extends downwardly to connect to one end of the blocking lever 120. One end of the other flexible link 154 is wound around the drum 152 and extends past the other diverting wheel 153 provided at the top end of the first upright 110, then extends horizontally to the second upright 110, and bypasses the one diverting wheel 153 provided at the top end of the second upright 110, and then extends vertically downward to be connected to the other end of the blocking lever 120.

The two flexible connectors 154 are identical in the direction of winding of the drum. The blocking means further comprises a lifting ring 190. A lifting ring 190 is connected to the end of the blocking lever 120. The flexible connection 154 is connected to a bail 190. Thus, the driving assembly 150 has a simple structure.

A flexible connector 154 extending in a vertical direction may be located within the recess 111. It will be appreciated that in embodiments not shown, the drive assembly may also include a rack and pinion mechanism, linear motor, or like structure capable of linear movement.

As shown in fig. 4 to 6, the blocking device further includes an initial blocking position sensor 161, an initial passing position sensor 162, and a controller. The drop-off preventing member 130 has a rod-shaped structure. The lengthwise direction of the drop-off preventing member 130 is parallel to the lengthwise direction of the upright post 110. The size of the drop-off preventing member 130 is greater than the size of the blocking lever 120 in the length direction of the column 110.

As shown in fig. 6, along the length direction of the pillar 110, the area through which the blocking lever 120 moves from the blocking start position to the blocking end position belongs to the blocking position of the blocking lever 120. As shown in fig. 6, when the blocking lever 120 is located at the blocking start position along the length direction of the upright post 110, the lower end of the blocking lever 120 is located at the substantially middle position of the anti-drop member 130. Along the length direction of the upright post 110, when the blocking lever 120 is located at the blocking end position, the lower end of the blocking lever is located at the lower end of the anti-drop member 130.

Referring to fig. 6, an initial blocking position sensor 161 is connected to the column 110. The initial blocking position sensor 161 is at the blocking lever 120 that has just moved to the blocking position (the blocking lever 120 at this time is located at the initial blocking position). The initial blocking position sensor 161 is used to acquire an initial blocking signal indicating that the blocking lever 120 has just moved to the blocking position.

As shown in fig. 5, along the length direction of the upright post 110, the area through which the blocking lever 120 moves from the passage start position to the passage end position belongs to the passage position of the blocking lever 120. As shown in fig. 5, in the longitudinal direction of the pillar 110, when the blocking lever 120 is located at the passage start position, the upper end of the blocking lever 120 is located at the axis of the output shaft of the driving member 151. Along the length of the upright 110, when the blocking lever 120 is in the end-of-traffic position, the upper end of the blocking lever is located at the upper edge of the spool 152.

Referring to fig. 5, an initial passing position sensor 162 is connected to the column 110. The initial passing position sensor 162 is at the blocking lever 120 that has just moved to the passing position (when the blocking lever 120 is in the passing start position). The initial pass position sensor 162 is used to collect an initial pass signal indicating that the blocking lever 120 has just moved to the pass position.

The controller is electrically connected to the initial blocking position sensor 161, the initial passing position sensor 162, and the drive assembly 150. The controller controls the operation of the driving assembly 150 to drive the blocking lever 120 to move.

When the controller acquires an initial blocking signal from the initial blocking position sensor 161, the driving assembly 150 is controlled to stop operating. When the controller obtains an initial pass signal from the initial pass position sensor 162, the drive assembly 150 is controlled to stop operation. Thereby, the movement of the blocking lever 120 can be automatically controlled.

As shown in fig. 5 and 6, the blocking device further includes an extreme blocking position sensor 163 and an extreme passing position sensor 164. The limit stop position sensor 163 is connected to the upright 110. The limit blocking position sensor 163 is located downstream of the initial blocking position sensor 161 in the direction in which the blocking lever 120 moves from the passing position toward the blocking position. The limit blocking position sensor 163 is at the blocking lever 120 (when the blocking lever 120 is in the blocking end position) that is about to leave the blocking position. The limit stop position sensor 163 is used to acquire limit stop signals. The limit stop signal indicates that the blocking lever 120 is about to leave the blocking position in a direction away from the passing position.

An extreme pass position sensor 164 is connected to the column 110. The limit pass position sensor 164 is located downstream of the initial pass position sensor 162 in the direction in which the blocking lever 120 moves from the blocking position toward the pass position. The limit passing position sensor 164 is at the blocking lever 120 (when the blocking lever 120 is in the passing end position) that is about to leave the passing position. The limit pass position sensor 164 is used to collect limit pass signals. The limit pass signal indicates that the blocking lever 120 is about to leave the passing position in a direction away from the blocking position.

The controller is electrically connected to the limit stop position sensor 163 and the limit pass position sensor 164. When the controller acquires the limit blocking signal, the driving assembly 150 is controlled to stop working. When the controller acquires the limit pass signal, the controller controls the stop of the driving assembly 150. Thus, when the initial blocking position sensor 161 is damaged, the controller may control the action of the driving assembly 150 according to the signal collected by the limit blocking position sensor 163. When the initial passing position sensor 162 is damaged, the controller may control the action of the drive assembly 150 according to the signal collected by the limit passing position sensor 164.

The position of the blocking lever in the passing position and the position of the blocking lever in the blocking position may be set as needed.

The controller may be electrically connected to the vehicle platform to control movement of the vehicle platform in a vertical direction. The controller controls the blocking lever 120 to move to the passing position when it is determined that the loading platform reaches the floor where the car hall is located. The controller controls the blocking lever 120 to move to the blocking position when it is determined that the loading platform does not reach the floor where the lobby is located. The position of the vehicle carrying platform can be acquired by a sensor electrically connected with the controller, so that the controller can determine whether the vehicle carrying platform reaches the floor where the car hall is located.

The controller can be electrically connected with the garage car hall door so as to control the opening or closing of the garage car hall door. The controller controls the blocking lever 120 to move to the passing position when it determines that the garage door is open. The controller controls the blocking lever 120 to move to the blocking position when it determines that the garage door is closed. The position of the garage car hall door can be acquired by a sensor electrically connected with the controller, so that the controller can determine whether the garage car hall door is opened or closed.

Preferably, the garage door may be a rollup door. Therefore, the garage door has a simple structure.

Preferably, the surface of the blocking lever 120 remote from the lifting channel is provided with a warning sign. Thus, the erroneous operation of the driver of the vehicle can be warned.
