Description

Technical Field

[0001] This invention relates to the field of vertical elevator technology, and more specifically, to an omnidirectional adjustable elevator door operator mounting bracket. Background Technology

[0002] Currently, the main installation methods for door operators are lintel installation (front wall installation), car top installation, and column installation (straight beam installation). Each of these methods has its advantages and disadvantages, but a common problem is the inconvenience they present on construction sites. Installation is complex and difficult, requiring significant time to adjust the door operator and door panels after initial installation to meet the requirements of various gaps in the elevator door system, resulting in a substantial time commitment for these methods.

[0003] Chinese Patent Publication No. CN207671516U, published on July 31, 2018, discloses an adjustable installation structure for an elevator door operator. This structure can adjust the distance between the door operator's back panel and the lintel, as well as the verticality of the door operator's back panel; however, it cannot adjust the position of the door operator in all directions. Summary of the Invention

[0004] This invention overcomes the problem that the existing door operator installation structure has limited adjustment of the door operator angle and cannot adjust the door operator angle in all directions. It provides an omnidirectional adjustable elevator door operator installation bracket that can adjust the door operator in all directions.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an omnidirectional adjustable elevator door operator mounting bracket, comprising:

[0006] The gantry crane bracket has bracket waist holes along its length.

[0007] Adjustable bracket, which cooperates with the outer side of the gantry crane bracket, and the gantry crane bracket is provided with adjustable waist holes that cooperate with the waist holes of the bracket;

[0008] A support cover is installed at the end of the gantry crane bracket, and the support cover has a support cover hole;

[0009] The positioning clip is set on the inner side of the gantry crane bracket. The positioning clip has at least two positioning bolt holes. The end of the positioning clip is provided with a positioning connecting plate. The positioning connecting plate is provided with a positioning connecting hole. The longitudinal adjusting bolt passes through the positioning connecting hole and the support cover hole and connects with the longitudinal adjusting nut.

[0010] The support bolt includes a support screw and a support disc located in the middle of the support screw;

[0011] One end of the support screw passes through the bracket waist hole and connects to the positioning bolt hole, while the other end of the support screw passes through the adjustment waist hole and connects to the gantry back plate; the support plate is set between the gantry bracket and the adjustment bracket and abuts against the adjustment bracket.

[0012] In this invention, the position of the gantry crane back panel can be adjusted by adjusting the position of the adjusting bracket. The position of the adjusting bracket can be adjusted by the longitudinal adjusting bolts and the supporting bolts, so that the adjusting bracket can be adjusted to any angle and position. It has the characteristics of simple installation structure and convenient use, and can realize the omnidirectional adjustment of the angle of the gantry crane back panel.

[0013] Preferably, the gantry crane back plate is provided with a gantry crane waist hole along its length, and the support screw passes through the gantry crane waist hole and is connected to the nut.

[0022] The combination of hydraulic holes and a sealed piston allows the support rod to form a floating support structure, enabling the support rod to be easily adjusted to any angle, thus providing support for an adjustable bracket at any angle.

[0023] Preferably, a support shaft hole is provided at the center of the support screw, and a side wall hole communicating with the support shaft hole is provided on the side wall of the hydraulic chamber. A locking piston is provided in the hydraulic chamber, and a locking rod is provided on the side wall away from the hydraulic chamber. The locking rod is slidably disposed in the side wall hole. A return spring is provided in the hydraulic chamber, and the return spring pushes the locking piston to move towards the support shaft hole. A threaded inner shaft is provided in the support shaft hole, and the end of the inner shaft abuts against the locking rod.

[0024] The inner shaft is designed to drive the locking piston, thereby enabling the control of the hydraulic bore and the hydraulic diameter bore to connect with the hydraulic chamber.

[0049] The technical solution of the present invention will be further specifically described below through specific embodiments and in combination with the drawings:

[0050] Embodiment 1: Refer to Figures 1 to 4 As shown, an omnidirectional adjustable elevator door machine mounting bracket includes a lintel back plate 1, a door machine back plate 2, a door machine bracket 3, an adjustment bracket 4, a support cover 5, a positioning strip 6 and a support bolt 7. The overall structure of the lintel back plate is L-shaped, and both ends of the lintel back plate 1 are connected with side end caps 11 through bolts.

[0051] The cross-section of the door machine bracket 3 is in a "U" shape. The concave side of the door machine bracket 3 is the inner side, and the protruding side is the outer side; a bracket waist hole 31 is provided along the length direction of the door machine bracket 3, and an installation waist hole 32 is provided at the end of the "U" opening of the door machine bracket 3. The door machine bracket 3 is fixedly connected to the lintel back plate 1 through the installation waist hole 32.

[0052] The adjustment bracket 4 is in a "C" shape. Similarly, the concave side of the adjustment is the inner side, and the protruding side is the outer side. The inner side of the adjustment bracket 4 cooperates with the outer side of the door machine bracket 3, and an adjustment waist hole 41 matching the bracket waist hole 31 is provided on the adjustment bracket 4.

[0053] The support cover 5 is arranged at the end of the door machine bracket 3. A support cover hole 51 is provided on the support cover. The support cover hole 51 is a through hole provided with threads. Support mounting plates 52 are provided on both sides of the support cover 5. Bolt holes are provided on the support mounting plates. The support mounting plates 52 are fixedly arranged on both sides of the end of the door machine bracket 3 through bolts.

[0054] The positioning strip 6 is arranged on the inner side of the door machine bracket 3. At least two positioning bolt holes 61 are provided on the positioning strip 6. The positioning bolt holes 61 are through holes with threads; a positioning connecting plate 62 perpendicular to it is fixedly arranged at the end of the positioning strip 6. A positioning connection hole 63 is provided on the positioning connecting plate 62. A longitudinal adjustment bolt 64 passes through the positioning connection hole 63 and the support cover hole and is connected to a longitudinal adjustment nut 65.

[0055] The support bolt 7 includes a support screw rod 71 and a support disc 72 fixedly arranged at the middle position of the support screw rod 71. The support disc 72 divides the support screw rod 71 into two parts, and threads are provided at both ends of the support screw rod 71.

[0056] In this embodiment, two support screws 71 are provided, respectively located at both ends of the adjusting waist hole 41 along its length. One end of the support screw 71 passes through the bracket waist hole 31 and connects to the positioning bolt hole 61, while the other end passes through the adjusting waist hole 41 and connects to the door operator back plate 2. The door operator back plate 2 has a door operator waist hole 21 along its length. The support screw 71 passes through the door operator waist hole 21 and connects to the nut, so that the door operator back plate 2 is fixedly mounted on the support screw 71. The support plate 72 is located between the door operator bracket 3 and the adjusting bracket and abuts against the inner side of the adjusting bracket 4.

[0057] The gantry crane bracket 3 has bracket bolts 33 and bracket screw holes 34 at both ends of the bracket waist hole 31. The bracket bolts 33 are fixed to the upper part of the gantry crane bracket 3 by welding, and the bracket screw holes 34 are threaded holes that pass through the lower part of the gantry crane bracket 3. The adjusting bracket 4 has adjusting holes 42 at both ends of the adjusting waist hole 41. The bracket bolts 33 pass through the upper adjusting holes 42 and are connected to the fixing nuts, and the fixing bolts 43 pass through the lower adjusting holes 42 and are connected to the bracket screw holes 34. In the above configuration, if the bracket bolts 33 are fixed to the lower part of the gantry crane bracket 3, the bracket bolts 33 will interfere with the gantry crane back plate 2 when it is installed. If the bracket screw holes 34 are set to the upper part of the gantry crane bracket 3, the fixing bolts 43 may interfere with the positioning clips when the gantry crane back plate 2 is installed.

[0058] The gantry crane bracket 3 has several guide bolts 35 arranged along its length on both side walls. In this embodiment, there are two guide bolts 35 on each side of the gantry crane bracket 3. The gantry crane bracket 3 has threaded holes, and the guide bolts 35 are connected to the threaded holes. The side walls of the adjusting bracket 4 have adjusting side holes 44 that cooperate with the guide bolts 35. The adjusting side holes 44 are arranged along the thickness direction of the adjusting bracket 4. Through the cooperation of the support screw 7171 and the adjusting side holes 44, when the adjusting bracket 4 moves relative to the gantry crane bracket 3 in the thickness direction of the gantry crane back plate 2, the guide bolts 35 can play a guiding role. In order to reduce friction, a support screw sleeve 36 is sleeved on the outside of the guide bolt 35.

[0059] Additionally, a reinforcing bracket 8 is included, positioned between the adjusting bracket 4 and the door operator bracket 3. A support plate 81, perpendicular to the bottom of the reinforcing bracket 8, is fixedly installed. The reinforcing bracket 8 has a reinforcing waist hole 82, and a reinforcing hole 83 is provided at the end of the reinforcing waist hole 82 near the support plate 81. During installation, the reinforcing hole 83 mates with the fixing bolt 43. The support screw 7171 below the adjusting waist hole 41 passes through the reinforcing waist hole 82 and the bracket waist hole 31, and is threaded into the positioning bolt hole 61. The support plate 81 has a support plate 81 hole. When the door operator bracket 3 is installed on the lintel back panel, bolts pass through the support plate 81 and are fixedly connected to the lintel back panel.

[0060] Furthermore, in this embodiment, a waist hole partition plate 311 is provided at the middle position of the waist hole 31 of the bracket to separate the waist hole 31. The waist hole partition plate 311 can connect the two sides of the waist hole 31 of the bracket, thereby improving the overall strength of the gantry crane bracket 3.

[0061] In this invention, two omnidirectional adjustable elevator door operator mounting brackets are installed along the length of the door lintel back panel during use, and the two omnidirectional adjustable elevator door operator mounting brackets are arranged in parallel; the door operator back panel 2 is connected to the mounting and support screws 7171.

[0062] The invention is used as follows: (1) When it is necessary to adjust the door machine back plate 2 up and down along the length of the door machine bracket 3, adjust the two omnidirectional adjustable elevator door machine mounting brackets at the same time. First, loosen the longitudinal adjusting nut 65, and then rotate the longitudinal adjusting bolt 64 to the appropriate position. During the rotation of the longitudinal adjusting bolt 64, it can drive the positioning clip 6 to move up and down. During the up and down movement of the positioning clip 6, it drives the support screw 7171 to move. The support screw 7171 drives the adjustment door machine bracket 3 to move up and down, thereby realizing the adjustment of the up and down position of the door machine back plate 2.

[0063] (2) When it is necessary to adjust the gantry backplate 2 horizontally (i.e., from the... Figure 4 When rotating clockwise and counterclockwise from the perspective of the elevator door operator, the roll adjustment can be achieved by simply adjusting the position of the longitudinal adjusting bolt 64 of the omnidirectional adjustable elevator door operator mounting bracket.

[0064] (3) When it is necessary to adjust the door machine back plate 2 back and forth (i.e., adjust along the thickness direction of the door machine back plate 2), adjust the two omnidirectional adjustable elevator door machine mounting brackets at the same time, loosen the fixing nuts and fixing bolts 43, and then pull the adjusting bracket 4 to move back and forth. When it moves to the appropriate position, rotate the support screw 7171 so that the support plate 72 can abut against the inner side of the adjusting bracket 4. Finally, tighten the fixing nuts and fixing bolts 43.

[0065] (4) When it is necessary to make lateral adjustment to the door machine back plate 2 (i.e., rotate clockwise or counterclockwise from the top view), only the position of the adjustment bracket 4 of the omnidirectional adjustable elevator door machine mounting bracket needs to be adjusted to achieve lateral adjustment;

[0066] (5) When it is necessary to adjust the pitch of the door operator back plate 2 (i.e., rotate clockwise or counterclockwise from the side view), the adjustment can be achieved by simply adjusting the position of one of the support screws 7171 on the omnidirectional adjustable elevator door operator mounting bracket.

[0067] (6) When it is necessary to adjust the back plate 2 of the door operator to the left or right, the door operator can be adjusted by means of the door operator waist hole 21 provided on the back plate 2 of the door operator.

[0068] The present invention has a simple structure and is easy to install. By rotating different bolts to adjust the position of the adjusting bracket 4, the position of the adjusting bracket 4 can be changed, thereby realizing the function of adjusting the door machine back plate 2.

[0069] Example 2: Refer to Figure 5 and Figure 6 As shown, this embodiment is structurally similar to Embodiment 1, except that a hydraulic sleeve 9 is provided on the support screw 71, and a support hole 721 is provided in the support plate 72. The diameter of the support hole 721 is larger than the diameter of the support screw 71. Several hydraulic holes 91 are provided in the circumferential direction of the end face of the hydraulic sleeve 9. The bottom of the several hydraulic holes 91 is connected to a hydraulic diameter hole 92. The several hydraulic diameter holes 92 are all connected to a hydraulic cavity 93 located in the center of the support screw 71. Hydraulic oil is provided in the hydraulic holes 91 and the hydraulic cavity 93. A sealing piston 94 is provided in the hydraulic hole 91. A piston rod 941 is provided at the bottom of the sealing piston 94 away from the hydraulic hole 91. Several support rods 73 are provided in the circumferential direction of the support plate 72. The support rods 73 and the piston rods 941 are connected by a universal joint. In this embodiment, there are six hydraulic holes 91 and six support rods 73.

[0070] A support shaft hole 711 is provided at the center of the support screw 71. A side wall hole 931 is provided on the side wall of the hydraulic chamber 93, which is connected to the end of the support shaft hole 711. A locking piston 95 is provided in the hydraulic chamber 93. A locking rod 951 is provided at the end of the locking piston 95 away from the hydraulic chamber 93. The locking rod 951 is slidably provided in the side wall hole 931. A return spring 96 is provided in the hydraulic chamber 93. The return spring 96 pushes the locking piston 95 to move towards the support shaft hole 711. A threaded inner shaft rod 712 is provided in the support shaft hole 711. The end of the inner shaft rod 712 abuts against the locking rod 951.

[0071] A rotating ball 731 is fixedly installed at the end of the support rod 73 near the support plate 72. A ball hole 722 is provided on the support plate 72. The rotating ball 731 and the ball hole 722 are configured to cooperate with each other.

[0072] In Embodiment 1, when the adjusted bracket 4 and the lintel back panel are not parallel, there is a certain angle between the adjusted bracket 4 and the lintel back panel. Since the support plate 72 is also parallel to the lintel back panel, the end face of the support plate 72 cannot be completely fitted with the adjusted bracket 4. The support plate 72 only partially supports the adjusted bracket 4, meaning that the support plate 72 cannot provide complete support for the adjusted bracket 4. Not only is the adjusted bracket 4 unstable, but the support plate 72 is also prone to deformation after long-term use, thus affecting the installation angle of the door operator back panel 2. Therefore, the problem solved by this embodiment is how to ensure that the adjusted bracket 4 at any angle can maintain parallel support with the support plate 72, so that the end face of the support plate 72 can fit with the adjusted bracket 4 regardless of the angle of the adjusted bracket 4, and provide good support.

[0073] The working principle of this embodiment is as follows: When the angle of the door operator back plate 2 needs to be adjusted, the inner shaft rod 712 is loosened, so that the inner shaft rod 712 releases the push on the locking rod 951. At this time, the locking piston 95 is pushed by the return spring 96. The return spring 96 pushes the locking piston 95 to move, so that all six hydraulic boreholes 92 are connected to the hydraulic chamber 93, and the hydraulic oil can flow freely in the hydraulic boreholes 92 and the hydraulic chamber 91. After the angle of the adjusting bracket 4 is adjusted, since the piston rod 941 is slidably set in the hydraulic chamber 91, the sealing piston 94 slides in the hydraulic chamber 91. This allows the support screw 71 to rotate, causing the support plate 72 and the support plate 951 to move. When the adjusting bracket 4 is in contact, the support plate 72 can automatically adjust its angle so that the end face of the support plate 72 can be completely in contact with the adjusting bracket 4. Then, the inner shaft 712 is rotated so that the inner shaft 712 moves into the support shaft hole 711. The end of the inner shaft 712 pushes the locking rod 951 into the hydraulic chamber 93, so that the locking piston 95 moves into the hydraulic chamber 93. The locking piston 95 blocks each hydraulic bore 92, so that a sealed cavity is formed in the hydraulic bore 91, so that the sealing piston 94 cannot slide in the hydraulic chamber 93, thereby allowing the piston rod 941 to support the support plate 72.

[0074] Therefore, through the above structural design, the end face of the support plate 72 can fit against the door operator back panel 2 regardless of the angle of the adjustment bracket 4, and achieve a good support effect.

[0075] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications may be made without departing from the technical solutions described in the claims.
