Description

Technical Field

[0001] The invention relates to the field of machinery, and in particular to a basement sliding door. Background Art

[0002] At present, large basement doors are generally rolling doors or flip-up doors. Usually, a transition passage is dug at the corresponding part of the ground at the top of the basement, and the basement door is set in the rear half of the transition passage, while the front half of the transition passage is open. The problems with existing basement doors are: 1. The open transition passage causes the ground road to be cut off, affecting the passage of people and vehicles, and there is also a safety hazard of people falling. 2. When the height of the items in the basement is greater than the depth of the basement, the basement door cannot be closed, which has a certain adverse effect on the safe and stable storage of items. 3. The basement door has a weak load-bearing capacity and cannot be ballasted. 4. When the width of the basement door increases, the basement door's own weight increases accordingly, and it is easy for the middle part to sag and sag, which not only affects the taking and placing of objects (such as goods, items or equipment) in the basement, but may even make it impossible to close the basement door. Summary of the invention

[0003] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art and to provide a basement sliding door. Through the cooperation of two sliding door panels and the lifting door panels on both sides, when the top opening of the basement is closed, the top surfaces of the two lifting door panels are flush with the top surfaces of the two sliding door panels and can be flush with the surrounding ground, so that the top of the basement is closed and constitutes a part of the ground for passage. When the top opening of the basement needs to be opened, the space at the top is avoided after the two lifting doors are lowered, and the two sliding door panels are opened and moved into the avoidance space respectively, so that the basement door is opened for taking and placing objects in the basement. It is conducive to passage and has sufficient bearing capacity, which is conducive to improving safety of use and is also convenient for the use of the basement.

When the two sliding door panels are closed, the two lifting door panels are in a raised state, and the top surfaces of the two lifting door panels are flush with the top surfaces of the two sliding door panels and can be flush with the surrounding ground, so that the top of the basement is closed and constitutes a part of the ground for passage. When the two lifting door panels are in a descending state, the space at the top is avoided after the two lifting doors descend, and the two sliding door panels are opened and moved into the avoidance space respectively, so that the basement door is opened for taking and putting objects into the basement. The technical solution cooperates with each other through two sliding door panels and lifting door panels on both sides. When the top opening of the basement is closed, the top surfaces of the two lifting door panels are flush with the top surfaces of the two sliding door panels and can be flush with the surrounding ground, so that the top of the basement is closed and constitutes a part of the ground for passage. When the top opening of the basement needs to be opened, the space at the top is avoided after the two lifting doors are lowered, and the two sliding door panels are opened and moved into the avoidance space respectively, so that the basement door is opened for taking and placing objects in the basement. It is conducive to passage and has sufficient bearing capacity, which is conducive to improving safety of use and is also convenient for the use of the basement.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0026] Example: Figure 1-Figure 9 As shown, a basement sliding door comprises a door frame 1 and a basement door matched with the door frame 1.

[0027] The difference between the present technical scheme and the prior art is that the basement door comprises lifting door panels 2 on both sides, and two sliding door panels 3 arranged between the two lifting door panels 2. When the two sliding door panels 3 are closed, the two lifting door panels 2 are in a raised state, and the top surfaces of the two lifting door panels 2 are flush with the top surfaces of the two sliding door panels 3 and can be flush with the surrounding ground, so that the top of the basement is closed and constitutes a part of the ground for passage. When the two lifting door panels 2 are in a descending state, the space at the top is avoided after the two lifting doors are descended, and the two sliding door panels 3 are opened and moved into the avoidance space respectively, so that the basement door is opened for taking objects into and putting them into the basement.

[0028] In the present technical solution, the two sliding door panels 3 and the lifting door panels 2 on both sides cooperate with each other. When the top opening of the basement is closed, the top surfaces of the two lifting door panels 2 are flush with the top surfaces of the two sliding door panels 3 and can be flush with the surrounding ground, so that the top of the basement is closed and constitutes a part of the ground for passage. When the top opening of the basement needs to be opened, the space at the top is avoided after the two lifting doors are lowered, and the two sliding door panels 3 are opened and moved into the avoidance space respectively, so that the basement door is opened for taking and placing objects in the basement, which is conducive to passage and has sufficient bearing capacity, is conducive to improving safety of use, and is also convenient for the use of the basement.

[0029] In practical applications, in order to make the sliding door panel 3 move more smoothly and help reduce the load of the sliding door panel 3 during the movement, a sliding support guide track 26 is set at the bottom of each sliding door panel 3. The sliding support guide track 26 has rollers, which can effectively reduce the actual load of the sliding door panel 3 during the movement.

[0030] Then further improve the above technical solution:

[0031] In actual application, several groups of lifting mechanisms are arranged at intervals under each lifting door panel 2, and each group of the lifting mechanisms includes a first power 4 and at least two telescopic support rods 5 driven by the first power 4. The first power 4 is used to drive the telescopic support rods 5 to extend to raise the lifting door panel 2 and provide support, or drive the telescopic support rods 5 to retract to lower the lifting door panel 2.

[0032] In the present technical solution, the lifting mechanism is used to enable the lifting door panel 2 to perform a lifting action, and at the same time to limit the descent of the lifting door panel 2. The lifting mechanism is arranged below the lifting door panel 2, and the support limit function is activated. When the lifting door panel 2 bears too much load or the lifting mechanism fails and the lifting door panel 2 cannot rise, a recessed area is formed in the area corresponding to the lifting door panel 2. The limit of the lifting mechanism ensures that the depth of the recessed area will not be too deep, and it is only the depth corresponding to the lifting and lowering amplitude of the lifting door panel 2, thereby preventing vehicles or pedestrians above from falling directly to the bottom of the basement, which can improve safety to a certain extent.

[0033] In actual application, several groups of safety mechanisms 6 are set under each lifting door panel 2. The safety mechanism 6 is used to support the lifting door panel 2 in a raised state, and is used to improve the load-bearing capacity of the lifting door panel 2. When the lifting door panel 2 descends, the safety mechanism 6 avoids the descending channel of the lifting door panel 2, so that the lifting door panel 2 can descend smoothly.

[0034] In the present technical solution, the provision of the safety mechanism 6 is conducive to further improving the safety of the lifting door panel 2 and ensuring the safety of pedestrians and vehicles passing through.

[0035] In this technical solution, the safety mechanism 6 is mainly used to support the state after being raised to the right position, so that the lifting door panel 2 always maintains a position flush with the ground and the translation door panel 3, which is conducive to the smooth and safe passage of pedestrians and vehicles. In actual application, three groups of safety mechanisms 6 are set under each lifting door panel 2, respectively set on the three adjacent sides of the lifting door panel 2, and avoid the side corresponding to the translation door panel 3, which is conducive to ensuring the support of the lifting door panel 2 and facilitating the translation of the translation door panel 3.

[0036] In actual application, the safety mechanism 6 includes a base 7, a supporting body 8 pivotally connected to the base 7 at the lower end, a second power driving the supporting body 8 to rotate, the supporting body 8 is in a long strip shape that widens from bottom to top, a supporting groove 9 is provided at the upper end of the supporting body 8, and an upwardly extending blocking wall 10 is provided on the outer side of the upper end of the supporting body 8, the outer end of the lifting door panel 2 is embedded in the supporting groove 9, the blocking wall 10 is used to resist the side wall of the outer end of the lifting door panel 2, and the bottom wall of the supporting groove 9 is supported by the bottom wall of the outer end of the lifting door panel 2.

[0037] In the present technical solution, the base 7 on the safety mechanism 6 can be fixed on a corresponding position on the ground, or can be fixed on the door frame 1 .

[0038] In practical applications, the basement sliding door further includes a third power 11, a translation mechanism driven by the third power 11, and the translation mechanism drives the two sliding door panels 3 to move in opposite directions to open the upper end of the basement; or to move the two sliding door panels 3 toward each other to close the upper end of the basement. The third power 11 simultaneously drives the two sliding door panels 3 to move synchronously, which is conducive to efficiently removing the two sliding door panels 3 to open the upper end of the basement, or efficiently closing the two sliding door panels 3 to close the upper end of the basement.

[0039] In actual application, the translation mechanism also includes a left and right rotating screw rod 12 driven by the third power 11, and a plurality of screw nuts arranged on the left and right rotating screw rod 12, and the screw nuts are respectively fixed at the bottom of the two translation door panels 3. The rotation of the left and right rotating screw rod 12 is used to make the corresponding screw nuts move in opposite directions to drive the two translation door panels 3 to move in opposite directions, or to make the corresponding screw nuts move toward each other to drive the two translation door panels 3 to move toward each other.

[0040] In this technical solution, the use of left and right rotating screws 12 can realize the two sliding door panels 3 to simultaneously translate back to each other for opening or to simultaneously translate toward each other for closing. It has high operating accuracy and reliable operation, and a relatively simple structure, which is conducive to ensuring that the third power 11 maintains stable operation for a long time and reduces the failure rate.

[0041] In actual application, the translation mechanism also includes two connecting shafts 13 driven by the third power 11, two steering mechanisms 14 respectively arranged at the outer ends of the two connecting shafts 13, there are two left and right rotating screw rods 12, each of the steering mechanisms 14 is respectively connected to the corresponding left and right rotating screw rods 12 one by one, the two connecting shafts 13 are respectively arranged on both sides of the third power 11 and are located on the same straight line, so that the two left and right rotating screw rods 12 respectively cooperate with the two sides of the two translation door panels 3.

[0042] In this technical solution, a set of third power 11 drives two connecting shafts 13 at the same time, and then the connecting shafts 13 form a one-to-one correspondence with the steering mechanism 14, so that the power of the third power 11 is transmitted to the two left and right screw rods 12 respectively, and the two left and right screw rods 12 are respectively arranged on both sides of the translation door plate 3. The left and right screw rods 12 and the corresponding screw nuts drive the two translation door plates 3 to perform corresponding actions synchronously to achieve door opening and closing. The overall structural design of the translation mechanism is ingenious, the overall structure is relatively simple, and the operation is stable and reliable.

[0043] In practical applications, the basement sliding door further includes a locking mechanism, which is used to close and lock the two sliding door panels 3 .

[0044] In the present technical solution, the locking mechanism is used to prevent the two sliding door panels 3 in the closed state from accidentally opening, which is beneficial to improving the safety of use and preventing pedestrians and vehicles from falling into the basement on the accidentally opened sliding door panels 3 and being injured or damaged.

[0045] In actual application, the locking mechanism includes a fourth power 15, a guide sleeve 16 matched with the output end of the fourth power 15, a locking shaft 17 arranged in the guide sleeve 16, a wedge mouth 19 with a small bottom and a large mouth is arranged at the outer end of the locking shaft 17, and the side walls of the two sliding door panels 3 respectively have a wedge-shaped portion 18, the wedge-shaped portion 18 is small on the outside and large on the inside, and the inclined surfaces on the wedge-shaped portions 18 on the two sliding door panels 3 are arranged back to back. The fourth power 15 is used to make the locking shaft 17 telescopic. When the locking shaft 17 is extended, it is used to make the two wedge-shaped portions 18 insert into the wedge mouth 19 to form a locking fit. When the locking shaft 17 is retracted, the two wedge-shaped portions 18 are separated from the restriction of the locking shaft 17, and the two sliding door panels 3 can be separated.

[0046] In actual application, a supplementary notch and a supplementary plate 21 cooperating with the supplementary notch are set on the sliding door panel 3, the shape of the supplementary plate 21 is adapted to the shape of the supplementary notch, a switching mechanism is set at the bottom of the supplementary plate 21 and the bottom of the sliding door panel 3, the switching mechanism includes a fifth power, a swing arm 22 cooperating with the fifth power, the swing end of the swing arm 22 is fixed to the bottom of the supplementary plate 21, a link seat 23 is set at the bottom of the sliding door panel 3, the driving end of the swing arm 22 is connected to the link seat 23, the fifth power drives the swing arm 22 to swing at the intersection on the link seat 23, so that the supplementary plate 21 swings up to close the supplementary notch and swings down to open the supplementary notch.

[0047] In this technical solution, the setting of the supplementary gap is used to facilitate the placement of equipment or items whose local height is greater than the depth of the basement in the basement, thereby increasing the use range of the basement and improving the utilization rate of the basement. When equipment or items whose local height is greater than the depth of the basement are placed in the basement, the supplementary gap is opened so that the part extends upward from the supplementary gap. In order to further improve the applicability of the basement, the setting position of the supplementary gap can be set according to actual conditions.

[0048] In the present technical solution, the link seat 23 is fixed on the bottom wall or end wall or other suitable position of the sliding door panel 3 .
