Description

Technical Field

[0001] This utility model relates to the field of lifting technology, and more specifically, to a safety protection device for a bridge gantry crane. Background Technology

[0002] Bridge cranes include both bridge cranes and gantry cranes, both of which belong to the category of bridge-type cranes. A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. Also known as an overhead crane, gantry crane, or hoist, various protective measures are currently required during crane operation to ensure safe operation, and wind-resistant anchoring is one of them.

[0003] Currently, during the windproof anchoring process of cranes, if the anchoring hole to be anchored deforms due to extreme weather and cannot provide sufficient pull-out force, the anchoring effect will be greatly weakened. At this time, it is necessary to activate the drive component inside the end beam to make the traveling wheel run along the I-beam track to adjust its position. This is not safe enough in windy weather, as the anchoring component cannot automatically adjust its position, and thus the windproof anchoring effect needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a safety protection device for bridge gantry cranes.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A safety protection device for a bridge gantry crane includes an end beam and an I-beam. The end beam is equipped with traveling wheels that cooperate with the I-beam. The traveling wheels are connected to a drive assembly fixed within the end beam. The device also includes four mounting brackets, a limit assembly, an anchoring box, a horizontal movement assembly, an anchoring assembly, and a double stabilizing assembly.

[0007] The mounting bracket has a placement groove that fits against the side wall of the end beam;

[0008] Limiting components are respectively installed on the end beam and the mounting bracket to ensure that the mounting bracket is accurately limited at both ends of the end beam;

[0009] The bottom-open anchor boxes are symmetrically welded onto the mounting frame;

[0010] The two sets of horizontally moving components that move synchronously are respectively installed in two anchor boxes;

[0011] The anchoring component is connected to a horizontally moving component;

[0012] The dual stabilizing components are symmetrically arranged on the mounting bracket and cooperate with the I-beam.

[0013] Furthermore, the limiting component includes limiting rollers, through holes, threads, and fastening nuts. Two sets of limiting rollers are symmetrically welded to both ends of the end beam. The through holes are opened on the mounting frame and are adapted to the corresponding limiting rollers. Each limiting roller is provided with threads, and a fastening nut is fitted on the threads.

[0014] The above solution uses a limiting component to enable quick installation and locking of the mounting bracket in the fixed area of ​​the end beam.

[0015] Furthermore, the horizontal movement component employs a lead screw assembly.

[0016] Furthermore, the anchoring component includes a telescopic component, a disc, and serrations. The telescopic component is fixed on the horizontal moving component, and the telescopic component is connected to the disc. Several serrations are arranged on the circumference of the disc.

[0017] The above scheme achieves multi-point anchoring and limiting of the crane by cooperating with the anchoring components and the pre-laid anchoring holes on the ground.

[0018] Furthermore, the dual stabilizing component includes auxiliary telescopic components, clamping plates, and rubber pads. Auxiliary telescopic components are symmetrically arranged on the mounting frame, and the auxiliary telescopic components are connected to clamping plates that are distributed opposite each other. Rubber pads are provided on the clamping plates and the rubber pads are in contact with the I-beams.

[0019] The above solution achieves double clamping and locking of the I-beam by having a double stabilizing component contact it, thereby improving the stability of the crane.

[0020] Furthermore, one of the anchor boxes is equipped with a wind pressure anemometer.

[0021] The above solution can detect the wind speed around the crane in real time using a wind pressure anemometer. If the wind speed exceeds the preset range, it will automatically send a signal to the controller to quickly start the windproof anchoring process.

[0022] Furthermore, a buffer is provided on the outer side of the mounting bracket.

[0023] When the crane trolley travels to the end of the I-beam rail, the buffer can absorb the impact kinetic energy through elastic or hydraulic deformation, reducing the collision force to within the structural tolerance range. This prevents the end beam, rail, and mounting frame from deforming or breaking due to overload, thus improving the safety protection effect of the crane.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] Compared to existing technologies, this device improves the windproof anchoring effect of the crane through multi-point anchoring. Furthermore, if extreme weather causes deformation of a set of anchor holes, rendering them unable to provide sufficient pull-out resistance, the anchoring components can be moved by the horizontal moving component to replace them with suitable anchor holes for re-fixing. This eliminates the need for a driving component to move the traveling wheels along the I-beam, ensuring efficient cooperation between the anchoring components and anchor holes. After anchoring, a dual stabilizing component clamps the I-beam to further enhance the crane's limiting effect. The combined effect of these two components results in a better limiting effect for the crane. The mounting frame and end beam are easy and secure to install, thus improving the crane's safety protection. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0033] like Figure 1 and Figure 2As shown, a safety protection device for a bridge gantry crane includes an end beam and an I-beam. The end beam is equipped with traveling wheels that cooperate with the I-beam. The traveling wheels are connected to a drive assembly (not shown in the figure) fixed inside the end beam. The device also includes four mounting brackets 1, a limiting assembly 2, an anchoring box 3, a horizontal movement assembly 4, an anchoring assembly 5, and a double stabilizing assembly 6.

[0034] The mounting bracket 1 has a placement groove 101 that fits against the side wall of the end beam;

[0035] Limiting components 2 are respectively installed on the end beam and the mounting frame 1 to ensure that the mounting frame 1 is accurately limited at both ends of the end beam;

[0036] The bottom-open anchor boxes 3 are symmetrically welded onto the mounting frame 1;

[0037] Two sets of horizontally moving components 4, which move synchronously, are respectively installed in two anchor boxes 3;

[0038] Anchoring component 5 is connected to horizontal movement component 4 (specifically, horizontal movement component 4 is a lead screw component);

[0039] The double stabilizing components 6 are symmetrically arranged on the mounting bracket 1 and cooperate with the I-beam.

[0040] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the limiting component 2 includes a limiting roller 21, a through hole, a thread, and a fastening nut 22. Two sets of limiting rollers 21 are symmetrically welded to both ends of the end beam. The through hole is opened on the mounting frame 1 and is adapted to the limiting roller 21. Each limiting roller 21 is provided with a thread, and a fastening nut 22 is fitted on the thread. The through hole and the thread are not shown in the figure.

[0041] Further refinements of the embodiments of this utility model, such as... Figure 2 As shown, the anchoring component 5 includes a telescopic member 51, a disc 52, and serrations 53. The telescopic member 51 is fixed on the horizontal moving component 4. The telescopic member 51 is connected to the disc 52. A number of serrations 53 are arranged on the circumference of the disc 52.

[0042] Further refinements of the embodiments of this utility model, such as... Figure 2 As shown, the double stabilizing component 6 includes an auxiliary telescopic component 61, a clamping plate 62, and a rubber pad 63. The auxiliary telescopic component 61 is symmetrically arranged on the mounting frame 1. The auxiliary telescopic component 61 is connected to the clamping plates 62 that are distributed opposite each other. The clamping plate 62 is provided with a rubber pad 63 and the rubber pad 63 is in contact with the I-beam.

[0043] In a further optimization of the above embodiment, the mounting frame 1 is provided with a telescopic rod connected to the clamping plate 62 to improve the stability of the auxiliary telescopic component 61 in windy weather and to improve its service life. The telescopic rod is shown in the figure without a number.

[0044] It should be noted that the horizontal moving component 4, the telescopic component 51, and the auxiliary telescopic component 61 are all electrically connected to the controller, which is not shown in the figure and is specifically located on the inside of the mounting bracket 1.

[0045] The working process of this utility model is as follows:

[0046] First, align the through hole on the mounting bracket 1 with the limiting roller 21 on the end beam and insert it (the two through holes on the mounting bracket 1 pass through the two limiting rollers 21 at one end of the end beam at the same time). At this time, the installation area of ​​the mounting bracket 1 on the end beam can be accurately defined. Then, the fastening nut 22 is used in conjunction with the thread on the limiting roller 21 to achieve quick and stable fixation between the end beam and the mounting bracket 1.

[0047] After the anchoring is completed, when a windproof anchoring process is required in windy weather, the telescopic component 51 drives the disc 52 to move down in coordination with the saw teeth 53, thereby engaging with a set of anchoring holes pre-laid on the ground to achieve anchoring. However, if the anchoring holes are deformed due to extreme weather and cannot provide sufficient pull-out resistance, the screw assembly can drive the anchoring component 5 to move back and forth to the anchoring holes of another set of cells (the two sets of adjacent anchoring holes are equidistant, and the range of motion of the screw assembly is pre-set). Then, the anchoring component 5 engages with the new set of anchoring holes. In this way, multiple mounting brackets 1 can be used to firmly anchor the end beam at both ends, and multi-point anchoring makes the windproof anchoring effect of the crane more secure.

[0048] After multi-point anchoring is completed, the auxiliary telescopic component 61 on the mounting frame 1 is moved by the controller, thereby driving the clamping plate 62 to contact the I-beam to achieve double clamping and locking of the I-beam, thus improving the stability of the crane. The rubber pad 63 contacts the I-beam to avoid wear on the I-beam during the double stabilization process, thus completing the double firm limit of the crane (windproof anchoring + I-beam firm clamping).

[0049] Compared to existing technologies, this device improves the windproof anchoring effect of the crane through multi-point anchoring. If extreme weather causes deformation of a set of anchoring holes, making it unable to provide sufficient pull-out resistance, the anchoring component 5 can be moved by the horizontal moving component 4 to replace the qualified anchoring hole and re-fix it. It does not require the driving component to drive the traveling wheel to move along the I-beam to ensure efficient cooperation between the anchoring component 5 and the anchoring hole. After anchoring, the I-beam can be clamped by the double stabilizing component to further improve the crane's limiting effect. The combination of the two makes the crane's limiting effect better. The installation frame 1 and the end beam are easy and firm to install, thus improving the safety protection effect of the crane.

[0050] In some embodiments, such as Figure 3 As shown, one of the anchoring boxes 3 is equipped with a wind pressure anemometer 7; in this embodiment, the wind pressure anemometer 7 can detect the wind speed of the environment around the crane in real time. If the wind speed exceeds the preset value range, it will automatically send a signal to the controller to quickly start the windproof anchoring process.

[0051] In other embodiments, such as Figure 4 As shown, a buffer 8 is provided on the outer side of the mounting frame 1. In this embodiment, when the crane trolley runs to the end of the I-beam rail, the buffer 8 can absorb the impact kinetic energy through elastic or hydraulic deformation, reduce the collision force to the range that the structure can withstand, and prevent the end beam, rail and mounting frame 1 from deforming or breaking due to overload, so as to make the crane's safety protection effect better.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
