Description

Technical Field

[0001] This utility model belongs to the field of crane technology, specifically relating to a protective device for a crane operator's cab. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. It is also called an overhead crane, gantry crane, or tire crane. The main feature of a tire crane is that its driving cab and lifting control cab are combined into one. It evolved from a crawler crane, replacing the crawler and traveling support parts of the traveling mechanism with a tire chassis, overcoming the disadvantage of crawler crane tracks damaging the road surface. It belongs to material handling machinery. A bridge crane is a lifting device that spans across workshops, warehouses, and material yards to lift and transport materials. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated structures on both sides, which can make full use of the space under the bridge frame to lift and transport materials without being obstructed by ground equipment. It is the most widely used and most numerous type of lifting machinery.

[0003] A review of announcement number CN204021004U reveals a protective device for excavator cabs. This technology discloses a "protective frame, wire mesh, movable hinges, upper fixed support, and lower fixed support. The wire mesh is fixed to the inner side of the protective frame. Movable hinges are located at the two corners at the upper end of the protective frame, and these hinges are connected to the upper fixed support. Lower fixed supports are located at the two corners at the lower end of the protective frame. The protective frame is fixed to the excavator cab shell by the upper fixed support and bolts. Its advantages include a novel, simple, and reasonable structure; the device is easy and convenient to install; the entire protective frame can rotate around the movable hinges, effectively covering the glass, blocking gravel, preventing gravel from damaging the cab glass, ensuring the driver's safety, and eliminating safety hazards."

[0004] While the design can effectively cover the glass, block gravel, prevent it from damaging the cab windows, and ensure the driver's safety and eliminate potential hazards, the connection between the device and the cab body is made by bolts. This can easily obstruct the driver's view when not in use. Furthermore, the simple structure relies solely on the rigidity of the material for protection when impacted, making it insufficient for cushioning.

[0005] To address the aforementioned problems, this application proposes a protective device for a crane operator's cab. Utility Model Content

[0006] The purpose of this utility model is to provide a protective device for a crane cab to solve the problems mentioned in the background art. By sliding between the anti-pressure rod and the guide groove, the anti-pressure rod and the connecting plate can switch between protective and retracted states, which can play an effective protective role during hoisting operations. Furthermore, under the deformation of the buffer spring and the telescopic spring, as well as the rotation of the anti-pressure rod and the connecting plate, the impact on the cab body can be buffered to a great extent, which can further ensure the personal safety of the driver.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A protective device for a crane operator's cab includes: a cab body, and a pressure-resistant rod installed inside the cab body.

[0010] Preferably, one end of the connecting piece and the telescopic spring are fixedly connected, and the other end of the telescopic spring is fixedly connected to the surface of the pressure-resistant rod. The pressure-resistant rods are equidistantly arranged above the partition plate, and each of the pressure-resistant rods is connected in series through the connecting piece. The connecting piece and the surface of the pressure-resistant rod are rotatably connected, while both ends of the pressure-resistant rod are slidably connected to the guide groove.

[0011] Preferably, the locking tongue is fixedly installed at the midpoint of the outermost anti-pressure bar, and the locking tongue and the latch are engaged and connected, while the latch is fixedly installed on the surface of the lifting plate.

[0012] Preferably, the surface of the connecting seat is fixedly connected to one end of the buffer spring, the other end of the buffer spring is fixedly connected to the surface of the slide rod, and the buffer spring is sleeved on the outside of the slide rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1 As shown:

[0025] A protective device for a crane operator's cab includes a cab body 1.

[0026] In this implementation plan: The existing announcement number CN204021004U discloses an excavator cab protection device. This technical means will not be described in detail here. For details on the improvement of this prior art, please refer to the disclosed technology below. In order to solve the technical problems existing in this prior art, such as the "connection between the device and the cab body 1 is by bolts when the device is performing protective work, which can easily affect the driver's vision when not performing hoisting work, and the structure is simple. When subjected to impact, it can only rely on the rigidity of its material to provide protection and is difficult to achieve the purpose of buffering", this problem is obviously a real and difficult problem to solve. In view of this, in order to solve the above problems, a pressure-resistant rod 6 and a connecting seat 9 are added on the basis.

[0027] Furthermore:

[0028] like Figure 1 - Figure 5 As shown:

[0029] In conjunction with the above, it also includes a pressure-resistant rod 6 installed inside the cockpit body 1. The two ends of the pressure-resistant rod 6 are connected to the guide groove 3 opened inside the cockpit body 1. Connecting pieces 7 are installed at equal intervals on the surface of the pressure-resistant rod 6. The pressure-resistant rod 6 and the connecting pieces 7 are installed at equal intervals inside the cockpit body 1. A locking tongue 8 is also provided on one side of the pressure-resistant rod 6. The locking tongue 8 is connected to the surface of the locking buckle 13. The locking buckle 13 is installed on the surface of the lifting plate 12. A sliding rod 11 connected to the connecting seat 9 is also provided on one side of the lifting plate 12.

[0030] In this implementation scheme: by sliding between the anti-pressure rod 6 and the guide groove 3, the anti-pressure rod 6 and the connecting piece 7 can switch between protective and storage states, which can play an effective protective role during hoisting operations. Furthermore, under the deformation of the buffer spring 10 and the telescopic spring 5, as well as the rotation of the anti-pressure rod 6 and the connecting piece 7, the impact on the cockpit body 1 can be buffered to a great extent, which can further ensure the personal safety of the driver.

[0031] Furthermore:

[0032] In an optional embodiment, the cockpit body 1 has an integrally formed partition 2 inside, and a sandwich layer is provided between the partition 2 and the cockpit body 1. Guide grooves 3 are opened on both sides of the sandwich layer, and a connecting piece 4 is fixedly installed on one side of the cockpit body 1.

[0033] In this embodiment: Under the action of the guide groove 3, the anti-compression rod 6 can move along the guide groove 3, so that when no hoisting work is being carried out, the anti-compression rod 6 can be stored between the cockpit body 1 and the bulkhead 2, and the connecting piece 4 can make the telescopic spring 5 have a stable connection point.

[0034] Furthermore:

[0035] In an optional embodiment, one end of the connecting piece 4 and the telescopic spring 5 are fixedly connected, and the other end of the telescopic spring 5 is fixedly connected to the surface of the pressure-resistant rod 6. The pressure-resistant rods 6 are equidistantly arranged above the partition plate 2. Each pressure-resistant rod 6 is connected in series through the connecting piece 7, and the connecting piece 7 and the surface of the pressure-resistant rod 6 are rotatably connected. The two ends of the pressure-resistant rod 6 are slidably connected to the guide groove 3.

[0036] In this embodiment, under the rotation of the anti-compression rod 6 and the connecting piece 7, it can deform to match the path of the guide groove 3 when performing protection and storage work. At the same time, it can play a protective role without significantly affecting the driver's vision.

[0037] Furthermore:

[0038] In an optional embodiment, the locking tongue 8 is fixedly installed at the midpoint of the outermost anti-pressure bar 6, and the locking tongue 8 and the latch 13 are engaged and connected, while the latch 13 is fixedly installed on the surface of the lifting plate 12.

[0039] In this embodiment, under the action of the locking tongue 8 and the locking buckle 13, the anti-pressure rod 6 and the lifting plate 12 can form a stable connection, so that when the anti-pressure rod 6 deforms, it can drive the sliding rod 11 and the buffer spring 10 to deform, providing a stable basis for the buffering of kinetic energy.

[0040] Furthermore:

[0041] In an optional embodiment, the surface of the connecting seat 9 is fixedly connected to one end of the buffer spring 10, the other end of the buffer spring 10 is fixedly connected to the surface of the slide rod 11, and the buffer spring 10 is sleeved on the outside of the slide rod 11.

[0042] In this embodiment: under the connection between the buffer spring 10 and the slide rod 11, the buffer spring 10 can be contracted when the slide rod 11 and the connecting seat 9 slide, thereby reducing the impact from external forces through the buffering effect of the buffer spring 10.

[0043] Furthermore:

[0044] In an optional embodiment, a slide bar 11 is also installed on the side of the lifting plate 12 away from the latch 13, and the surface of the slide bar 11 is slidably connected to the connecting seat 9.

[0045] In this embodiment, the connection between the slide rod 11 and the connecting seat 9 allows the anti-pressure rod 6 and the connecting piece 7 to achieve a buffering effect when subjected to impact, through the sliding of the connecting seat 9 and the slide rod 11, thus ensuring the safety of the driver.

[0046] The working principle and usage process of this utility model are as follows: When performing high-risk hoisting work, the driver can pull the locking tongue 8. At this time, the locking tongue 8 will drive the anti-pressure rod 6 to slide along the guide groove 3. When the anti-pressure rod 6 moves, the anti-pressure rod 6 will rotate with the connecting piece 7. At the same time, the other side of the anti-pressure rod 6 will pull the extension spring 5 on one side of the connecting piece 4 to extend. When the locking tongue 8 reaches the position of the locking buckle 13, the locking tongue 8 and the locking buckle 13 can be engaged. The anti-pressure rod 6 and the connecting piece 7 will block the glass and the driver. When an external object hits the cab, the anti-pressure rod 6 and the connecting piece 7 will be impacted by kinetic energy first. At this time, the locking buckle 13 will drive the lifting plate 12 and the sliding rod 11 to slide along the connecting seat 9. At the same time, the sliding rod 11 will also cooperate with the connecting seat 9 to compress the buffer spring 10. The extension spring 5 on the other side of the anti-pressure rod 6 will also bear the tension and perform stable buffering work on the impact, thereby effectively protecting the driver.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
