Description

Technical Field

[0001] The utility model relates to the technical field of fixing devices, in particular to a crane rail welding fixing device. Background Art

[0002] Crane tracks are rails installed on the ground or supporting structure to carry and guide the crane. Cranes are guided by tracks, allowing them to move and operate horizontally. They are widely used in factories, docks, warehouses, and other locations to improve efficiency during production and transportation. To ensure safe and smooth operation of cranes on tracks, the tracks must be securely fixed to the ground or supporting structure to avoid safety hazards caused by loosening, shifting, or deforming the tracks.

[0003] However, traditional crane rail fixtures have several drawbacks, particularly in terms of adaptability and flexibility. Once fixed with traditional welding, the rail's position is essentially immutable, complicating maintenance and adjustments when the rail needs to be relocated or recalibrated. Furthermore, welded fixtures often lack sufficient flexibility to accommodate varying work environments and rail specifications. Utility Model Content

[0004] The purpose of the utility model is to provide a crane rail welding and fixing device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crane rail welding fixture, comprising a base and a fixture body, wherein the fixing device body is provided at both ends of the top surface of the base, a base is provided inside the fixing device body, slots are provided on both sides of the surface of the base, an insert is slid inside the slot, a bottom plate is provided on the surface of the insert, and a second fixing hole is opened through the inside of the bottom plate.

[0006] When using a crane rail welding fixture in this technical solution, the staff needs to install it first. The staff will stick the base inside the fixture body to the position to be installed. When sticking, it is necessary to align the installation according to the position of the bolt installed on the base, so that the fourth fixing hole opened on the surface of the base is aligned with the bolt. After alignment, the base is lowered and moved and stuck to the surface of the base. At this time, the staff takes the nut and screws it on one end of the bolt to fix the base. After the base is fixed and installed, the staff takes the pressure plate and sticks it on the surface of the bottom plate. After sticking, the first fixing hole is aligned with the second fixing hole. The holes are aligned, and gaskets and washers are placed on the surface of the first fixing hole in sequence. After placement, screws are screwed into the overlapping first fixing hole and the second fixing hole. After the screws are screwed in, they will be directly inserted into the inside of the third fixing hole. Continue to screw until one end of the pressure plate is tightly pressed against the two side surfaces of the rail and then stop screwing to complete the installation of the utility model. When the staff finds that the installation position of the pressure plate needs to be recalibrated, the staff only needs to screw one end of the screw to make it leave the inside of the third fixing hole, so that the base plate can be moved directly on the surface of the slot, and the pressure plate can be moved indirectly, thereby completing the quick calibration operation of the pressure plate.

[0007] Preferably, a pressure plate is provided on the surface of the base plate, and a first fixing hole is formed through the pressure plate, and screws are inserted into the first and second fixing holes. The first and second fixing holes cooperate with the screws to securely connect the pressure plate to the base plate, achieving a secure connection and allowing the two ends of the pressure plate to press against the base plate surface and the two sides of the rail, respectively.

[0008] Preferably, a gasket is provided on the surface of the first fixing hole, and a washer is provided on the surface of the gasket. Through the cooperation of the gasket and the washer, the screw does not directly contact the surface of the first fixing hole when it is screwed on it, achieving the effect of raising, isolating, and preventing damage without contact.

[0009] Preferably, a third fixing hole is provided in the middle of the surface of the base, into which a screw is inserted. The third fixing hole allows one end of the screw that has passed through the first and second fixing holes to be inserted into the third fixing hole and thereby restrain the bottom plate and the pressure plate, thereby preventing the bottom plate and the pressure plate from being moved or repositioned without authorization.

[0010] Preferably, leakage holes are provided at both ends of the slot to allow water that accidentally enters the slot to flow out, thereby preventing it from accumulating inside the slot and causing corrosion damage thereto and affecting the sliding of the plug.

[0011] Preferably, the four corners of the base are provided with fourth fixing holes, into which bolts are inserted. The fourth fixing holes are provided so that the bolts can be inserted therein and matched with nuts to fix the fixing device body 3 on the surface of the base.

[0012] Preferably, the bolt is fixed to the top surface of the base, and a nut is rotatably mounted on the top of the bolt. Through the cooperation of the bolt and the nut, the fixing device body can be installed on the surface of the base, achieving a fixed installation effect.

[0013] Preferably, a steel rail is provided in the middle of the top surface of the base, and pressure plates are provided on both sides of the steel rail. By providing the steel rail, a device such as a crane can move on the surface, thereby achieving the effect of providing a mobile position.

[0014] Preferably, the slot and the insert are both designed with a convex structure. The convex structure design allows the insert to be limited when moving in the slot to prevent shaking, and the convex structure design allows the insert to slide stably in the slot.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The advantage of the present invention is that the position of the pressure plate can be flexibly adjusted through the adjustable connection between the screw and the base plate. The base plate is slidably installed in the slot using an insert, so that the pressure plate can be accurately positioned according to demand, solving the problem of poor adaptability of traditional welding fixtures. The pressure plate can be fixed or adjusted by turning the screws, which greatly improves the maintenance convenience and flexibility of the track fixture and adapts to a variety of working environments and track specifications.
