Description

Technical Field

[0001] The utility model relates to the technical field of elevator bracket welding, in particular to a welding tooling for elevator bracket cross beams. Background Technique

[0002] The elevator bracket cross beam is a key component in elevator installation. It is mainly used to support and fix the guide rails and bear the weight of relevant structures. The elevator bracket cross beam and the ring beam are usually important elements in the hoistway design together. They ensure the stable operation of the elevator, provide guidance for the elevator car, and bear the weight of the entire elevator system.

[0003] As an important component of elevator installation, the elevator bracket cross beam undertakes the task of supporting the overall weight of the elevator. In the existing technology, when butt-welding the cross beams, the operation usually includes manually padding gaskets at the bottoms of the two cross beams and then using a welding machine for welding. During this process, inaccurate positioning may occur during butt-joint, the welding efficiency is low, and the fitting condition of the two welded elevator bracket cross beams cannot be fully guaranteed, resulting in insufficient weld connection strength and thus the welding quality not meeting the standard.

[0004] Therefore, it is necessary to propose a welding tooling for elevator bracket cross beams to accurately position the welding of elevator bracket cross beams, ensure the fitting of welding points, and thus ensure the welding quality of elevator bracket cross beams. Content of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings in the existing technology and propose a welding tooling for elevator bracket cross beams.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A welding tooling for elevator bracket cross beams includes an auxiliary welding tooling mechanism, and an elevator bracket cross beam one and an elevator bracket cross beam two are clamped inside the auxiliary welding tooling mechanism; the auxiliary welding tooling mechanism includes a sleeve frame, an active clamping plate is slidably installed inside the sleeve frame, an upper backing plate is fixedly installed on the lower side of the active clamping plate, a lower backing plate is fixedly installed at the bottom of the sleeve frame, a threaded rod is rotatably installed on the active clamping plate, the threaded rod is screwed through above the sleeve frame, a rotating disk is fixedly installed at the upper end of the threaded rod, a support column is fixedly installed at the upper end of the rotating disk, and a round hole slot, a hexagonal hole slot and a square hole slot are fixedly installed on the side of the support column.

[0008] Preferably, the sleeve frame is of a rectangular frame structure.

[0009] Preferably, the sleeve frame is made of cast iron material and an anti-rust coating is applied on the surface of the sleeve frame.

[0010] Preferably, clamping bumps are fixedly installed on both sides of the movable clamping plate, through grooves are formed on both sides of the sleeve frame, and the clamping bumps are slidably clamped inside the through grooves.

[0011] Preferably, a reinforcing protective cylinder is fixedly installed on the upper side of the sleeve frame, and the reinforcing protective cylinder is screwed and sleeved outside the threaded rod.

[0012] Preferably, a receiving ring is fixedly installed on the upper side of the movable clamping plate, the receiving ring is rotatably sleeved outside the threaded rod, and a plurality of sliding balls are installed on the inner wall of the receiving ring. There is no thread setting at the intersection of the threaded rod and the receiving ring.

[0013] Preferably, a clamping convex head is fixedly installed at the lower end of the threaded rod, a clamping groove is formed inside the movable clamping plate, and the clamping convex head is rotatably clamped with the clamping groove.

[0014] Compared with the related art, a welding tooling for an elevator support beam proposed by the present utility model has the following beneficial effects:

[0015] In the present utility model, for the welding tooling for an elevator support beam, through the arranged auxiliary welding tooling mechanism, the elevator support beam to be welded is placed inside the sleeve frame. By rotating the rotary disk, the threaded rod fixedly connected to the bottom of the rotary disk can be driven to rotate. When the threaded rod rotates, it is screwed through the sleeve frame. Through the screw drive effect, its lower end gradually drives the movable clamping plate to move downward, stably clamping and fixing the elevator support beams stacked and placed inside the sleeve frame. When it is difficult to rotate the rotary disk when clamping the elevator support beam, the circular hole groove, hexagonal hole groove and square hole groove arranged on the rotary disk can be inserted with an auxiliary rod for rotation, increasing the acting torque on the rotary disk, making it more labor-saving when clamping and fixing the elevator support beam, improving the practicability. At the same time, the design of multiple use hole grooves enables the present utility model to be applicable to auxiliary rods with various cross-sectional shapes, enhancing the applicability. Through the clamping effect of the auxiliary welding tooling mechanism, the welding points of the two support beams to be welded are more accurate and not easy to slide, and at the same time, the welding points are made to fit together, ensuring the welding quality during the welding construction. Moreover, the structure of the present utility model is small and portable. When the welding point is long, several groups of auxiliary welding tooling mechanisms can be added to achieve a perfect fit of the welding points to ensure the welding quality.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figures 1-3 An elevator support beam welding tool comprises an auxiliary welding tool mechanism 3, wherein the auxiliary welding tool mechanism 3 clamps an elevator support beam 1 and an elevator support beam 2 inside.

[0022] In this embodiment, the auxiliary welding tooling mechanism 3 includes a sleeve frame 31, a movable splint 32 is slidably installed on the inner side of the sleeve frame 31, an upper pad 33 is fixedly installed on the lower side of the movable splint 32, a lower pad 34 is fixedly installed on the bottom of the sleeve frame 31, a threaded rod 39 is rotatably installed on the movable splint 32, the threaded rod 39 is screwed through to the top of the sleeve frame 31, a turntable 310 is fixedly installed on the upper end of the threaded rod 39, a pillar 311 is fixedly installed on the upper end of the turntable 310, and a circular hole groove 312, a hexagonal hole groove 313 and a square hole groove 314 are fixedly installed on the side of the pillar 311.

[0023] Through the above structure, the circular hole groove 312, the hexagonal hole groove 313 and the square hole groove 314 are provided on the pillar 311. When it is difficult to rotate the threaded rod 39 during use, the auxiliary rod can be inserted into the inner side of the hole groove that matches its shape. Then, the auxiliary rod is rotated to increase the torque on the turntable 310, making it easier to rotate the turntable 310. In addition, the design of multi-shaped hole grooves makes it suitable for auxiliary rods with various cross-sectional shapes, thereby enhancing the applicability of the utility model.

[0024] In this embodiment, the sleeve frame 31 is a rectangular frame structure, the sleeve frame 31 is made of cast iron material, and the surface of the sleeve frame 31 is coated with an anti-rust coating.

[0025] Through the above structure, the design of the cast iron material enables the sleeve frame 31 to have a higher structural strength, and the anti-rust coating applied on the surface of the sleeve frame 31 enables the sleeve frame 31 to have a higher corrosion resistance.

[0026] In this embodiment, engaging protrusions 36 are fixedly mounted on both sides of the movable clamping plate 32 , and through slots 35 are formed on both sides of the sleeve frame 31 , and the engaging protrusions 36 are slidably engaged with the inner sides of the through slots 35 .

[0027] Through the above structure, the sliding engagement design of the engaging protrusion 36 and the through slot 35 makes the movable clamping plate 32 more stable as it slides up and down driven by the threaded rod 39, and also has a stable clamping force when clamping the welding component, ensuring that the welding points do not slide against each other.

[0028] In this embodiment, a reinforcing casing 38 is fixedly installed on the upper side of the sleeve frame 31, and the reinforcing casing 38 is threadedly sleeved on the outside of the threaded rod 39. A receiving ring 37 is fixedly installed on the upper side of the movable splint 32, and the receiving ring 37 is rotatably sleeved on the outside of the threaded rod 39 and a number of sliding balls are installed on the inner wall of the receiving ring 37. There is no thread setting at the intersection of the threaded rod 39 and the receiving ring 37.

[0029] Through the above structure, the setting of the protective tube 38 is strengthened, and the screw engagement area of the threaded rod 39 is increased, which makes the screw driving force of the threaded rod 39 more stable and avoids the recurrence of thread slippage. The setting of the sliding ball on the inner wall of the receiving ring 37 reduces the rotational friction between the threaded rod 39 and the receiving ring 37.

[0030] In this embodiment, a clamping protrusion 315 is fixedly mounted on the lower end of the threaded rod 39 , and a clamping groove 316 is formed on the inner side of the movable clamping plate 32 , and the clamping protrusion 315 is rotatably clamped with the clamping groove 316 .

[0031] Through the above structure, the locking rotation setting of the locking protrusion 315 and the locking groove 316 enables the threaded rod 39 to eliminate the rotation effect of the threaded rod 39 on the locking groove 316 when the threaded rod 39 rotates and moves up and down, and the locking effect enables the locking protrusion 315 at the end of the threaded rod 39 to have an upward or downward locking force on the locking groove 316, thereby ensuring that the movable splint 32 is not disturbed by the rotation of the threaded rod 39 when it moves downward following the threaded rod 39.

[0032] In the present utility model, during use, the elevator support beam to be welded is placed inside the sleeve frame 31. The rotary disk 310 is rotated, driving the rotation of the threaded rod 39 fixedly installed at the lower end of the rotary disk 310. Then, under the driving action of rotational screwing, the threaded rod 39 moves downward on the sleeve frame 31. The lower end of the threaded rod 39 drives the movable clamping plate 32 to move downward, clamping the two elevator support beams to be welded between the upper backing plate 33 and the lower backing plate 34. If it feels strenuous during clamping, an auxiliary rod can be used. According to the cross-sectional shape of the auxiliary rod, it is inserted into the corresponding hole groove. At this time, rotating the other end of the auxiliary rod can increase the torque on the rotary disk 310, making the clamping process more labor-saving. When the two elevator support beams are clamped to a fitting state, the welding work can be carried out. After the welding is completed, rotate the rotary disk 310 in the reverse direction, driving the movable clamping plate 32 to move upward, and then slide the entire auxiliary welding tooling mechanism 3 out from the side of the elevator support beam.

[0033] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic features of the present utility model, the present utility model can be implemented in other specific forms.
