Description

Technical Field

[0001] The utility model relates to the field of security, in particular to a brake hydraulic control system for a silver pavilion rolling door. Background Art

[0002] Rolling shutter doors are made of multi-jointed door panels connected in series. The doors rotate up and down around the scroll above the door in a fixed slide. Rolling shutter doors are commonly used in shops, supermarkets, shopping malls, banks and other occasions.

Due to the particularity of silver pavilions, they have higher requirements for security, and their strength requirements are higher than ordinary rolling shutter doors. However, its overall structure is not much different from conventional rolling shutter doors. In the silver pavilion, if some special circumstances occur, the rolling shutter door will be quickly released, so that the silver pavilion can be quickly closed. Among them, in order to realize the retraction and release of the rolling shutter door, a motor is used to drive the retraction and release of the rolling shutter door. Since the rolling shutter door is heavy, a combination of a motor and a reducer will be used. This structure cannot achieve the rapid descent of the rolling shutter door. It is considered that when unwinding, the motor and the reducer will be separated from the reel of the rolling shutter door, so that the rolling shutter door can be quickly released. However, in this way, the rolling shutter door can be quickly released, but if this structure is quickly released, the impact force will be very large. In order to ensure the safety of equipment and personnel, it is considered to adopt a brake disc and a brake caliper structure. The brake disc is installed at the end of the reel, and the brake caliper is used to clamp the brake disc. By braking the brake disc, the unwinding of the reel is decelerated or braked. However, how to achieve accurate clamping, deceleration and braking of the brake disc by the brake caliper to prevent the rolling door from falling and causing damage to the equipment or injuring people is a direction that technical personnel in this field need to work on.

DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0029] Example 1: See Figure 1 , 2 As shown, a hydraulic control system for the brake of a Yinting rolling shutter door comprises a hydraulic driving component and a hydraulic pump 32 mounted on a fixed component 31, wherein the driving end of the hydraulic driving component is in contact with or connected to the piston rod of the hydraulic pump 32;

[0030] The hydraulic drive component includes a first motor assembly 33, a lead screw 34 and a slider assembly 35. One end of the lead screw 34 is threadedly connected to the slider assembly 35, and the other end is connected to the first motor assembly 33. The first motor assembly 33 is configured to drive the lead screw 34 to rotate, and drive the slider assembly 35 to be close to or away from the first motor assembly 33 through the lead screw 34.

[0031] The end of the slider assembly 35 away from one end of the lead screw 34 is in contact with or connected to the piston rod of the hydraulic pump 32, and the slider assembly 35 is slidably disposed on the fixed component 31;

[0032] A baffle 36 is movably installed between the first motor assembly 33 and the slider assembly 35. A limit switch 37 and a limit member 38 are provided on the fixed component 31. The limit switch 37 and the limit member 38 are arranged between the baffle 36 and the first motor assembly 33. The limit switch 37 is electrically connected to the first motor assembly 33.

[0033] In this embodiment, the silver pavilion special rolling door has a rotating shaft, a door body, and a driving mechanism. One end of the door body is connected to the rotating shaft, and the driving mechanism is used to drive the rotating shaft to rotate, so that the rotating shaft drives the door body to roll up, that is, the rolling door is opened. In order to achieve the rapid closing of the rolling door, the driving mechanism and the end of the rotating shaft can be separated or connected. When the rolling door needs to be driven to open, the driving mechanism is connected to the end of the rotating shaft, so that the rotating shaft can be driven to rotate, thereby achieving the rolling up of the door body and the opening of the rolling door. In order to achieve rapid closing of the rolling door, after the driving mechanism and the end of the rotating shaft are separated, the deadweight of the door body will drive the rotating shaft to unwind automatically. A brake disc is arranged at the other end of the rotating shaft, and a brake caliper is arranged outside the brake disc. Since the deadweight of the door body of the Yinting special rolling door is very large, the descending speed will be relatively fast. If it descends directly to the bottom, there will be a collision between the door body and the ground, resulting in damage to the equipment and the ground. At the same time, if there are people or things under the door body, there is a particularly large safety hazard. Therefore, by arranging a brake disc and a brake caliper, when the door body drops to a certain position, or when it is detected that there are people or things under the door body, the hydraulic control system supplies oil to the brake caliper, wherein the brake caliper is a hydraulic brake caliper, and the brake caliper is driven to clamp the brake disc by supplying oil to the brake caliper, and the clamping force of the brake caliper on the brake disc is achieved by the amount of oil supply, thereby achieving deceleration or braking of the brake disc, that is, achieving deceleration or braking during the closing process of the rolling door, preventing damage to the equipment or the hands of personnel, and ensuring safety of use.

[0034] Among them, in order to adjust the oil supply amount of the brake caliper, the first motor assembly is used to drive the rotation of the lead screw, so that one end of the lead screw is connected to the output end of the first motor assembly, and its end position is fixed, and the other end is screwed to the slider assembly, and its end position is also fixed. Therefore, the lead screw is limited by the first motor assembly and the slider assembly so that the lead screw can only rotate. During the rotation of the lead screw, the slider assembly is driven to move axially, so that the slider assembly approaches or moves away from the first motor assembly. In this process, since the end of the slider assembly is in contact or connection with the piston rod of the hydraulic pump, when the slider assembly is away from the first motor assembly, it will approach the hydraulic pump, and it will push the piston rod of the hydraulic pump to push, and the piston rod drives the piston at its end to push the hydraulic oil in the hydraulic pump out. Among them, the end of the hydraulic pump has a hydraulic oil pipe, which will be connected to the brake caliper. When the hydraulic oil is pushed into the brake caliper, it will push the brake pad of the brake caliper close to the brake disc through the corresponding components in the brake caliper, and the brake disc is braked by the brake pad in the brake caliper. When the first motor assembly drives the lead screw to rotate in the opposite direction, it drives the slider assembly to move toward the first motor assembly, that is, the slider assembly moves away from the hydraulic pump. During this process, the piston rod in the hydraulic pump may reset itself, or the slider assembly drives the piston rod to withdraw. During this process, the hydraulic oil in the brake caliper gradually returns to the hydraulic pump, thereby gradually reducing the clamping force of the brake caliper on the brake disc, reducing the braking force until the brake caliper does not contact the brake disc. In order to ensure that the first motor assembly stops working and waits for the next brake signal to restart the first motor assembly, a baffle, a limit member and a limit switch are set. When the lead screw rotates in the opposite direction and drives the slider assembly to approach the first motor assembly, it will contact the baffle after moving to a certain position, and then push the baffle to move toward the first motor assembly. When the baffle contacts the limit switch, the limit switch transmits a signal to the first motor assembly. At this time, the first motor assembly stops working and waits for the next brake signal. In order to prevent the baffle from moving excessively and damaging the limit switch, and to prevent the slider from moving excessively, a limit piece will be set, and the limit piece will be used to mechanically limit the baffle, thereby preventing the baffle from moving excessively toward the limit switch, thereby ensuring the quality of the limit.

[0035] The slider assembly 35 is movable between a first position and a second position, wherein the first position is close to the first motor assembly 33, the second position is far from the first motor assembly 33, and the first position is between the first motor assembly 33 and the second position;

[0036] When the slider assembly 35 moves to the first position, the slider assembly 35 pushes the baffle 36 to move toward the first motor assembly, and makes the end surface of the baffle 36 abut against the limit switch 37 and the limit member 38 .

[0037] In this embodiment, taking the direction shown in the figure as an example, the first motor assembly is on the left, the hydraulic pump is on the right, and the first position is on the left of the second position. When the slider assembly is in the first position, the slider assembly passes through the limit of the baffle, the limit member and the limit switch, and the slider assembly cannot move to the left. When the slider assembly is in the second position, the slider assembly moves to the right into place, and the brake caliper completes the braking.

[0038] See also Figure 2 As shown, a reset member 39 is also provided on the fixed member beside the limit member 38 or the limit switch 37, and the reset member 39 gives the baffle 36 a thrust to move toward the slider assembly 35;

[0039] When the slider assembly 35 moves to the first position, the baffle 36 abuts against the reset member 39;

[0040] When the slider assembly 35 is away from the first position, the reset member 39 pushes the baffle 36 to move toward the slider assembly 35 and prevents the baffle 36 from contacting the limit member 38 and the limit switch 37 .

[0041] In this embodiment, for example, rubber, spring or other elastic structure, taking the direction shown in the figure as an example, a slide rail, a connecting groove or other guide limit mechanism (not shown in the figure) is arranged on the fixed component, the baffle is slidably connected with the fixed mechanism, and its sliding direction is parallel to the axial direction of the lead screw. By setting a reset member, the reset member gives the baffle a push or pull to the right. When the slider assembly moves to the right (in this embodiment, all directions are taken as an example of the direction shown in the figure), the slider assembly will move away from the baffle. In this process, the reset force of the reset member directly pushes the baffle to move to the right, so that the baffle is out of contact with the limit switch. When the slider assembly moves to the left, after the slider assembly moves to the left to a certain extent, the left end of the slider assembly will first contact the baffle, and then continue to move to the left. In this process, the slider assembly will push the baffle to move to the left and squeeze the reset member. After the baffle contacts the limit switch (at this time, the baffle will also contact the limit member), the limit switch will feedback data to the first motor assembly and the entire control system of the corresponding silver pavilion rolling door, and the first motor assembly will stop working. There can be multiple reset members, so that the baffle is more evenly stressed. At the same time, with the reset member, the baffle moves a shorter distance, preventing the occurrence of a stuck phenomenon, and the baffle does not need to occupy too much moving space.

[0042] The middle of the baffle 36 is provided with a clearance hole, and the middle of the lead screw is inserted into the clearance hole. The limit switch and the limit member are respectively located at both ends of the lead screw, and are not arranged on one side, so that the force on the baffle is more uniform. The clearance hole is used for the lead screw to give way, and does not affect the normal rotation of the lead screw.

[0043] See also Figure 1 , 2 As shown, the first motor assembly 33 includes a first motor and a first reducer, the end of the lead screw 34 is connected to the output shaft of the first reducer via a coupling 331, and the first motor drives the lead screw 34 to rotate via the first reducer and the coupling 331.

[0044] In this embodiment, the first motor drives the lead screw to rotate via the first reducer and the coupling, thereby driving the slider assembly to slide and be arranged close to or away from the first motor assembly to achieve precise control of the hydraulic pump.

[0045] Among them, each rotation of the lead screw can push the slider assembly to move a precise predetermined distance, thereby accurately controlling the amount of hydraulic oil delivered by the hydraulic pump, thereby adjusting the braking force of the brake caliper to achieve deceleration or stopping of the rolling door.

[0046] See also Figure 1 , 2 As shown, the slider assembly 35 includes a slider 351 and a slider limiting portion 352. The slider limiting portion 352 is installed on the fixed component 31. A slide groove 353 with two ends passing through the slider limiting portion 352 is provided in the slider limiting portion 352. The slider 351 is slidably set in the slide groove 353, and the lead screw 34 is threadedly connected to the slider 351.

[0047] Among them, the slider limiting part can be composed of multiple slider blocks, for example, two slider blocks are used, which are relatively arranged on opposite sides of the slider, and the slider is limited by the two slider blocks so that the slider can only move laterally, or four slider blocks are used, which are respectively located on the four outer sides of the slider. The four slider blocks form a square structure, thus forming a slide groove, and the slider is limited by the slide groove, so that the slider can only move along the slide groove, thereby realizing the precise operation of driving the hydraulic pump, thereby ensuring the precise operation of the brake caliper.

[0048] See also Figure 1 , 2 As shown, a slider screw hole 354 is provided in the slider 351 , and the end of the lead screw 34 is threadedly connected to the slider screw hole 354 . When the lead screw 34 rotates, the slider 351 is driven to move along the slide groove.

[0049] The setting of the slider screw hole is used for threaded connection with the lead screw, wherein the slider and the slide groove are non-cylindrical structures, and the outer surfaces of the slide groove and the slider match, so that when the lead screw rotates, the slider cannot rotate relative to the slide groove. Therefore, the rotation of the lead screw will push the slider to move along the slide groove, thereby realizing the operation of the hydraulic pump.

[0050] When the lead screw drives the slider to move away from the hydraulic pump, the end surface of the slider facing the baffle plate contacts the baffle plate and pushes the baffle plate against the limit switch and the limit member.

[0051] In the utility model, the limit switch is a micro switch.

[0052] See also Figure 1 As shown, the fixing component 31 includes a first fixing plate 310, a first steel pipe 311 and a first connecting plate 312, the first steel pipe 311 is arranged on one side of the first connecting plate 312, the first motor assembly 33, the slider assembly 35, the baffle 36, the limit switch 37 and the limit member 38 are installed on the first connecting plate 312, one end of the first fixing plate 310 is connected to the first steel pipe 312, the hydraulic pump 32 is connected to the first steel pipe 311 via the hydraulic pump fixing member 313, and the first connecting plate 312 is connected to the first steel pipe 311 via the first connecting member 314.

[0053] Among them, the first connecting plate is used for the installation of the first motor assembly, slider assembly, baffle, limit switch and limit member. The first connecting plate and the hydraulic pump are connected and fixed through the hydraulic pump fixing frame, the first connecting member and the steel pipe respectively. The first fixing plate is used to connect the steel pipe and the Yinting rolling door, thereby realizing the connection and fixation of the brake hydraulic control system.
