Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to an elevator guide rail lifting device. Background Art

[0002] Elevator guide rails are mainly used for continuous vertical or inclined transportation between floors or on slopes. They are assembled from multiple sections of segmented elevator guide rails, which are convenient for loading, unloading and transportation. Due to the large size of the segmented elevator guide rails, a lifting device is required to lift them when loading and unloading them. The existing lifting device is relatively long in overall length and has sufficient lifting distance to lift the larger segmented elevator guide rails, while being relatively thin in width, making the overall weight lighter and reducing the impact on the output efficiency of the lifting device. However, due to its slender structure, this type of lifting device has a small contact area with the ground when placed on the ground, and has a high center of gravity, making it prone to rollover and extremely prone to safety accidents. Utility Model Content

[0003] The purpose of this application is to solve the above problems and provide an elevator guide rail lifting device to solve the technical problem that the existing elevator guide rail lifting device is prone to rollover.

[0004] To achieve the above-mentioned purpose, the present application provides an elevator guide rail lifting device, comprising: a beam, a lifting part is provided at the top of the beam, lifting ropes are installed at both ends of the beam, an anti-tilt seat is provided at the bottom of the beam, and there are two anti-tilt seats, which are symmetrically arranged at the two ends of the bottom of the beam. The anti-tilt seat includes a base, a support part and two limiting parts. The support part is arranged on the base, and the limiting part is relatively arranged at the top of the support part along the width direction of the beam. The beam is limited between the two limiting parts and extends along the width direction of the beam. The length of the base is greater than the width of the beam.

[0005] Compared with the prior art, the elevator guide rail lifting device of the present invention has a simple structure and is easy to operate. When the lifting device is placed on the ground, it can prevent the beam from tipping over, thereby greatly improving the safety factor during operation.

[0006] In one embodiment, the support portion comprises two vertical bars, a horizontal bar, and a reinforcing bar. The vertical bars are arranged on the base in a direction opposite to each other along the width of the crossbeam. The horizontal bar connects the top ends of the two vertical bars. The horizontal bar, the vertical bars, and the base enclose a hollowed-out rectangular space. The reinforcing bar is disposed within the rectangular space, and the two stoppers are disposed on the tops of the horizontal bars. The combination of the horizontal bar, the reinforcing bar, and the two vertical bars forms a stable support structure, thereby improving the stability of the elevator guide rail lifting device during placement.

[0007] In one embodiment, the reinforcing rod vertically connects the two vertical rods and further includes a reinforcing assembly comprising a connecting rod and two diagonal rods. The connecting rod spans the two anti-roll seats and is fixed to the two reinforcing rods. The diagonal rods obliquely connect the connecting rods and the base, forming an "eight"-shaped structure. The addition of the reinforcing assembly improves the support portion's anti-overturning capability and the overall stability of the anti-roll seat.

[0008] In one embodiment, the crossbars, the reinforcing bars, the vertical bars, the connecting bars, and the diagonal bars are all fixed by welding. By welding the crossbars, the reinforcing bars, the vertical bars, the connecting bars, and the diagonal bars, the structural strength, stability, and durability of the support portion are significantly improved.

[0009] In one embodiment, the crossbar, the reinforcement bar, the vertical bar, the connecting bar, and the diagonal bar are all hollow structures. The hollow structures of the crossbar, the reinforcement bar, the vertical bar, the connecting bar, and the diagonal bar make the anti-roll seat and the reinforcement assembly lighter and improve the load-bearing capacity.

[0010] In one embodiment, the base is provided with a U-shaped groove with an upward opening, and the bottoms of the vertical rods and the diagonal rods are fixed in the U-shaped groove. Fixing the bottoms of the vertical rods and the diagonal rods in the U-shaped groove can ensure the stability of the entire support portion in the vertical direction.

[0011] In one embodiment, the invention further comprises lifting rings, which are fixed to both ends of the crossbeam and to which the lifting rope is connected. The provision of the lifting rings facilitates the connection of the lifting rope to the crossbeam, thereby improving installation convenience.

[0012] In one embodiment, the number of lifting rings at one end of the beam is 4, arranged along the length of the beam. Different lifting rings can be selected for lifting according to the volume of the elevator guide rail to meet the lifting requirements in different scenarios.

[0013] In one embodiment, the lifting rings are symmetrically arranged on both sides of the crossbeam. The symmetrical arrangement of the lifting rings ensures uniform distribution of the load on the crossbeam, thereby improving the stability and safety of the entire lifting device.

[0022] Please refer to 1. This embodiment provides an elevator guide rail lifting device, which includes a beam 1, a lifting part 11 is provided on the top of the beam 1, lifting ropes 2 are installed at both ends of the beam 1, and an anti-tilt seat 3 is provided at the bottom of the beam 1. There are two anti-tilt seats 3, which are symmetrically arranged at the two ends of the bottom of the beam 1. The anti-tilt seat 3 includes a base 31, a support part 32 and two limiting parts 33. The support part 32 is arranged on the base 31, and the limiting part 33 is relatively arranged at the top of the support part 32 along the width direction of the beam 1. The beam 1 is limited between the two limiting parts 33 and extends along the width direction of the beam 1. The length of the base 31 is greater than the width of the beam 1. When the beam 1 is subjected to an external force that may cause it to roll over, the limit portion can limit the lateral movement of the beam, and the width and shape of the base will generate an anti-rollover moment opposite to the external force. This moment will resist the rollover tendency of the beam 1, thereby maintaining the stability of the lifting device, and the base can cause the center of gravity of the lifting device to shift downward, making it less likely to tilt or roll over.

[0023] The lifting portion 11 has a lifting hole 111 in the middle thereof. An operator can use a lifting tool such as a sling or hook through the lifting hole 111 to lift the elevator guide rail, eliminating the need for complex bundling and securing operations. This saves time and labor costs and improves operational efficiency. In other embodiments, the number of the lifting holes 111 can be two, three, or another number, and can be symmetrically arranged on the lifting portion 11.

[0024] The cross-sections at both ends of the crossbeam 1 are "I"-shaped, and the cross-section of the crossbeam 1 between the two anti-tilt seats 3 is a "T"-shaped. In the absence of the anti-tilt seats 3, the elevator guide rail lifting device can also be placed on the ground through the "I"-shaped cross-section of the crossbeam 1, thereby increasing the contact area with the ground and playing a certain anti-tilt role. The cross-section of the crossbeam 1 between the two anti-tilt seats 3 is a "T"-shaped cross-section, which can reduce the weight of the crossbeam 1 to a certain extent and facilitate transportation. In another embodiment, the cross-section of the crossbeam 1 between the two anti-tilt seats 3 can also be an "I"-shaped cross-section.

[0025] Please also refer to Figure 2The support portion 32 is composed of two vertical rods 321, a horizontal rod 322, and a reinforcing rod 323. The vertical rods 321 are arranged on the base 31 along the width of the crossbeam 1. The horizontal rod 322 connects the top ends of the two vertical rods 321. The horizontal rods 322, the vertical rods 321, and the base 31 enclose a hollowed-out rectangular space. The reinforcing rod 323 is located within this rectangular space, and the two stoppers 33 are located on the tops of the horizontal rods 322. The combination of the horizontal rods 322, the reinforcing rod 323, and the two vertical rods 321 forms a stable support structure, improving the stability of the elevator guide rail lifting device during placement. Furthermore, the hollowed-out rectangular space enclosed by the horizontal rods 322, the vertical rods 321, and the base 31 reduces the weight of the entire support portion 32 and optimizes space utilization. This ensures that the support portion 32 provides sufficient support while being lightweight and easy to carry and install.

[0026] The reinforcing rod 323 vertically connects the two vertical rods 321. The lifting device also includes a reinforcing assembly 4, which includes a connecting rod 41 and two diagonal rods 42. The connecting rod 41 spans the two anti-roll seats 3 and is fixed on the two reinforcing rods 323. The diagonal rod 42 obliquely connects the connecting rod 41 and the base 31, and the two diagonal rods 42 form an "eight"-shaped structure. The connecting rod 41 in the reinforcing assembly 4 spans the two anti-roll seats 3 and is fixed on the two reinforcing rods 323, forming an additional horizontal support layer, which effectively enhances the stability of the support part 32 in the horizontal direction. At the same time, the fixed connection between the connecting rod 41 and the reinforcing rod 323 also strengthens the connection strength between the vertical rods 321, making the entire structure more stable. The diagonal rods 42 enable the structure to better disperse and resist these forces when subjected to lateral forces, thereby avoiding structural failure caused by overturning.

[0027] The cross bar 322, the reinforcing bar 323, the vertical bar 321, the connecting rod 41 and the diagonal bar 42 are all fixed by welding. By welding and fixing the cross bar 322, the reinforcing bar 323, the vertical bar 321, the connecting rod 41 and the diagonal bar 42, an inseparable whole is formed, thereby greatly improving the structural strength, stability and durability of the entire anti-tilt seat 3. In this embodiment, the cross bar 322, the reinforcing bar 323, the vertical bar 321, the connecting rod 41 and the diagonal bar 42 are all square tubes, which are convenient for welding. In other embodiments, the cross bar 322, the reinforcing bar 323, the vertical bar 321, the connecting rod 41 and the diagonal bar 42 can also be round tubes or pipes of other shapes.

[0028] The crossbar 322, the reinforcing bar 323, the vertical bar 321, the connecting bar 41, and the diagonal bar 42 are all hollow structures. The hollow structure makes the anti-tilt seat 3 and the reinforcing assembly 4 lighter, facilitating transportation and installation, and improving the load-bearing capacity of the lifting device, thereby reducing costs and increasing efficiency.

[0029] The base 31 is provided with an upwardly opening U-shaped groove 311, into which the bottoms of the vertical rods 321 and the diagonal rods 42 are fixed. Securing the bottoms of the vertical rods 321 and the diagonal rods 42 within the U-shaped groove 311 ensures the vertical stability of the entire support portion 32, preventing the support portion 32 from tilting or collapsing when subjected to external forces. Furthermore, the hollow structure of the U-shaped groove 311 reduces the weight of the base 31 while maintaining sufficient strength and stability, reducing material costs and facilitating handling and installation.

[0030] The lifting device also includes a lifting ring 5, which is fixed to both ends of the beam 1, and the lifting rope 2 is connected to the lifting ring 5. The provision of the lifting ring 5 facilitates the connection of the lifting rope 2 to the beam 1, thereby improving the convenience of installation. Specifically, the lifting ring 5 is welded and fixed to the side wall of the beam 1, thereby improving the structural strength, stability and durability of the lifting ring 5. In another embodiment, the lifting ring 5 is detachably connected to the beam 1. The lifting ring 5 includes a U-shaped body 51 and a bolt 52, and threaded holes are provided at both ends of the U-shaped body 51. The bolt 52 is threadedly connected to the threaded hole to realize the opening and closing of the opening of the U-shaped body 51, so that the lifting rope 2 can be inserted into the U-shaped body 51.

[0031] The crossbeam 1 has four lifting rings 5 ​​arranged along its length. Different lifting rings 5 ​​can be selected based on the volume of the elevator guide rails to meet the lifting requirements of different scenarios. Furthermore, when lifting heavier elevator guide rails, multiple lifting rings 5 ​​can be used simultaneously to coordinate the lifting, distributing the load and improving stability during the lifting process. In other embodiments, the crossbeam 1 may have three, five, or other lifting rings.

[0032] The lifting rings 5 ​​are symmetrically arranged on either side of the crossbeam 1. This symmetrical arrangement ensures even load distribution on the crossbeam 1, avoids structural imbalance caused by load bias, and helps reduce bending and twisting of the crossbeam 1 during lifting, thereby improving the stability and safety of the entire lifting device. Furthermore, the symmetrical arrangement of the lifting rings 5 ​​provides greater flexibility during lifting operations. Whether performing single-point or multi-point lifting, the operator can select the appropriate combination of lifting rings 5 ​​based on the shape and weight of the elevator guide rails, thus meeting the lifting requirements of different scenarios.

[0033] The specific examples described above further illustrate the purpose, technical solutions and beneficial effects of this application. It should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
