Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to a novel quick-installation automatic position correction platform column structure. Background Art

[0002] The backpack rack platform system is mainly used in villa elevators as a platform for carrying passengers. In order to ensure the installation of passengers, the safety requirements are very high. At the same time, since this structure is generally installed in villa elevators, the villa elevator has a compact structure and is not easy to operate and install, so the installation convenience of the structure is also very important. At present, there are two main types of backpack rack platform structures on the market: one is that the platform is welded to the vertical beam, and the other is that the vertical beam and the platform are connected by bolts.

[0003] The platform and the vertical beam are welded together: The advantage of this structure is that it can ensure that the fixing strength between the platform and the vertical beam is more reliable. Due to the application of welding technology, this structure has higher stability and safety in actual use. However, it also has the following disadvantages. First, the overall volume of the backpack rack with this structure is large, which is not convenient for packaging, transportation and carrying. Secondly, since the welded parts cannot be disassembled, it is quite difficult to adjust the matching position of the platform and the vertical beam.

[0004] The vertical beam and the platform are connected with bolts, and the platform and the vertical beam are made into two parts: this structure is easy to pack and ship, and the matching position of the platform and the vertical beam can be adjusted slightly; however, all the direct forces between the platform and the vertical beam must be borne by the bolts, and the strength requirements of the bolts are very high. If the bolts are not strong enough, there is a risk that the platform may fall off the vertical beam. Summary of the invention

[0005] The purpose of the utility model is to provide a novel quick-install automatic position correction platform column structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel quick-install automatic position correction platform column structure, comprising a column, a column beam and a platform bottom plate, a plurality of column beams are connected between two parallel columns, the platform bottom plate is installed on the lower end surface of the column, and an upper card plate, a front card plate, a rear card plate and a lower card plate are connected in sequence from top to bottom between the columns below the column beams, the upper end of the front card plate is connected to the front side of the upper card plate, the lower end of the rear card plate is connected to the rear side of the lower card plate, and the upper card plate, the front card plate, the rear card plate and the lower card plate form a reinforcing rib end receiving groove;

[0007] The platform bottom plate comprises a bottom plate body, a plurality of reinforcing ribs arranged at the bottom of the bottom plate body and a concealing plate arranged at the end of the bottom plate body, and the end of the reinforcing rib is clamped in the accommodating groove at the end of the reinforcing rib.

[0008] Preferably, a plurality of force-dividing vertical ribs are connected between the bottommost column cross beam and the upper clamping plate.

[0009] Preferably, the reinforcing rib comprises a reinforcing rib body with a cross-section of an "X" shape and a clamping portion, and a group of clamping portions are arranged opposite to each other at the ends of the reinforcing rib body, and the clamping portions match the accommodating grooves at the ends of the reinforcing rib.

[0010] Preferably, the clamping portion is L-shaped, and the connection between its transverse portion and the longitudinal portion is clamped at the connection between the rear clamping plate and the lower clamping plate, and the top of its longitudinal portion is clamped at the connection between the upper clamping plate and the front clamping plate.

[0011] Preferably, the corners of the L-shaped clamping portion are provided with transition fillets.

[0012] Technical effects and advantages of the utility model:

[0013] 1. The column structure of this quick-install automatic position correction platform matches the vertical beam and the platform together through a unique mechanical structure. The more weight the platform carries, the better the matching stability, thereby ensuring the structural strength of the backpack rack platform. There is no need to worry about structural failure due to bolt failure. During installation, the platform is directly placed on the corresponding position of the vertical beam without adjusting the position. The platform will automatically adjust its position on the vertical beam through gravity, making installation more convenient.

[0014] 2. The structural design is simple. Through the combination of columns, column beams and platform bottom plates, the purpose of rapid assembly is achieved. The platform bottom plate is connected to the rib end receiving groove under the column beam through the reinforcing rib, which ensures the automatic correction position of the platform and reduces the installation and adjustment time.

[0015] 3. The reinforcing rib end receiving groove composed of the upper pallet, front side pallet, rear pallet and lower pallet effectively enhances the stability of the structure and improves the durability of the platform. The design of the force-dividing vertical ribs further disperses the force borne by the columns and beams, and enhances the bearing capacity of the structure.

[0016] 4. The cross-section of the reinforcement rib is designed to be in the shape of a "J", which ensures strength and reduces weight. The L-shaped clamping part on the reinforcement rib body matches the accommodating groove at the end of the reinforcement rib, achieving a quick and stable connection. The transition fillet design at the corner of the L-shaped clamping part reduces stress concentration and improves the reliability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The platform base plate 3 includes a base plate body 31, a plurality of reinforcing ribs 32 arranged at the bottom of the base plate body 31, and a concealing plate 33 arranged at the end of the base plate body 31. The end of the reinforcing rib 32 is clamped in the accommodating groove at the end of the reinforcing rib, ensuring the automatic correction position of the platform and reducing the installation and adjustment time.

[0031] Preferably, a plurality of force-dividing vertical ribs 8 are connected between the bottommost column beam 2 and the upper clamping plate 7, so as to further disperse the force borne by the column beam 2 and enhance the bearing capacity of the structure.

[0032] Preferably, the reinforcing rib 32 comprises a reinforcing rib body 321 with a cross-section of an I-shaped shape and a clamping portion 322 , a group of clamping portions 322 are disposed opposite to each other at the ends of the reinforcing rib body 321 , and the clamping portions 322 match the accommodating grooves at the ends of the reinforcing rib.
