Description

Technical Field

[0001] This application relates to the field of elevator car structure component technology, and in particular to a safety support connection device for elevator car frame installation. Background Technology

[0002] Elevators are classified as special equipment. They are electromechanical devices that use power to lift or transport people or goods by means of a car that runs along rigid guide rails or steps that run along a fixed path. They include passenger elevators, escalators, and moving walkways. The precise, safe, and efficient installation of the car frame is a key technical indicator for ensuring the safety, stability, and comfort of passenger elevators.

[0003] The existing car frame consists of components such as an upper beam, a lower beam, columns, and tie rods, which serve to fix and suspend the car. Guide shoes are fixed at both ends of the upper and lower beams to guide the car to move up and down along the guide rails and maintain the car's horizontal position in the hoistway. Safety clamps are installed on the columns and lower beams respectively. When the elevator falls at excessive speed, the safety clamps can clamp the car onto the guide rails under the action of the speed governor. There is also a fixed rope suspension plate or a car top anti-rope pulley at the upper beam to suspend the car.

[0004] The aforementioned car frame requires the use of small lifting machinery during installation, which has a certain impact on the precise positioning of various connecting parts. Multiple adjustments are needed to meet the technical requirements, indicating areas for improvement. Utility Model Content

[0005] In order to meet the needs of on-site installation of elevator car frames and achieve precise positioning of each connection part, thereby reducing the number of adjustments required to meet technical requirements, this application provides a safety support connection device for elevator car frame installation.

[0006] This application provides a safety support connection device for elevator car frame installation, which adopts the following technical solution:

[0007] A safety support connection device for installing an elevator car frame includes a support beam, a column fixed to the side wall of the support beam, an upper beam fixed to the end of the column away from the support beam, and an extension beam fixed to the side wall of the upper beam. It also includes fasteners, and the support beam, the column, the upper beam, and the extension beam are all fixed by the fasteners.

[0008] By adopting the above technical solution, when workers install the car frame, they assemble the support beam and the column with fasteners, then assemble the column and the upper beam with fasteners. At this time, workers assemble the extension beam to the end of the upper beam away from the column with fasteners. Workers complete the assembly of the safety support connection device. When on-site installation is required, workers directly use the assembled parts for installation. This setting meets the needs of on-site installation of the car frame, achieves precise positioning of each connection part, and thus reduces the number of adjustments required to meet technical requirements.

[0009] Optionally, rectangular grooves are provided at both ends of the support beam, and several connecting holes are provided on both sides of the support beam.

[0010] By adopting the above technical solution, the rectangular groove facilitates the installation of the support beam on the elevator car frame by the staff, and the connection hole facilitates the assembly of the support beam and the column by the staff, thereby improving the efficiency of the staff in installing the support beam.

[0011] Optionally, the connecting holes are provided in two rows and in several columns, with the two rows of connecting holes arranged opposite to each other.

[0012] By adopting the above technical solution, the setting of two rows of connecting holes reduces the possibility of the column swaying after it is installed on the support beam, thereby increasing the stability of the structure.

[0013] Optionally, the end of the column is provided with a mounting hole, which is arranged opposite to the connection hole.

[0014] By adopting the above technical solution, the mounting holes are designed to facilitate the alignment of the mounting holes with the connection holes, thereby improving the installation accuracy and reducing the number of adjustments required.

[0015] Optionally, several connecting holes are also provided on both sides of the upper beam, and the connecting holes are opened in the same way. The mounting hole is also provided at the end of the column away from the supporting beam.

[0016] By adopting the above technical solution, the columns can be installed from any direction, which facilitates the assembly of support beams, columns, and upper beams by the workers and improves the installation efficiency of the workers.

[0017] Optionally, the upper beam has several mating holes on the side away from the column, and the side wall of the extension beam has several alignment holes, with the mating holes and alignment holes being arranged opposite each other.

[0018] By adopting the above technical solution, the alignment hole setting improves the installation accuracy of workers when installing the beam, thereby further increasing the efficiency of workers installing the beam.

[0019] Optionally, the sidewall of the extension beam is also provided with a semi-enclosed groove, which is located at the end of the extension beam away from the column.

[0020] By adopting the above technical solution, the semi-enclosed groove makes it easier for workers to fix the extension beam in the working environment, thereby improving the working performance of the extension beam.

[0021] Optionally, the fasteners include fastening bolts, fastening nuts, and washers.

[0022] By adopting the above technical solution, the combination of fastening bolts, fastening nuts and washers improves the assembly efficiency of the safety support connection device. When parts are missing, workers can easily assemble new parts directly onto the device, increasing the service life of the safety support connection device.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the workers install the car frame, they connect the support beam to the column, the column to the upper beam, and the upper beam to the extension beam using fasteners. At this time, the workers can directly install the assembled safety support connection device onto the elevator. This setting meets the needs of on-site installation of the car frame, achieves precise positioning of each connection part, and thus reduces the number of adjustments required to meet technical requirements.

[0025] 2. When assembling the column, the worker aligns the mounting hole with the connection hole, and then installs the fasteners onto the inner wall of the mounting hole and the connection hole. The setting of the mounting hole and the connection hole improves the installation accuracy of the worker and reduces the number of adjustments required for the worker to assemble the column.

Rectangular grooves 6 are provided at both ends of the support beam 1. The rectangular grooves 6 are preferably semi-circular arcs. Several connecting holes 7 are provided on both sides of the support beam 1. In this embodiment, the connecting holes 7 are preferably processed vertically in two rows and three columns with equal diameters in six places.

[0034] Reference Figure 1 and Figure 2 The column 2 is an equilateral rectangular square tube structure. In this embodiment, the column 2 is preferably made of Q-253A material and is formed by cutting and drilling. Several mounting holes 8 are opened at both ends of the column 2. In this embodiment, sixteen mounting holes 8 are preferably processed vertically at equal intervals and equal diameters at four planes at both ends of the column 2. Two holes are processed at each plane at each end. The diameter and spacing of the mounting holes 8 are the same as those of the connecting holes 7. The mounting holes 8 and the connecting holes 7 are arranged opposite to each other.

[0035] Reference Figure 1 and Figure 3The upper beam 3 has an inverted equilateral U-shaped structure. In this embodiment, the upper beam 3 is preferably made of Q-253A material, and the hot-rolled steel plate is cut, bent at room temperature, and drilled. The upper side of the upper beam 3 is provided with several butt holes 9, and the two sides of the upper beam 3 are provided with several connecting holes 7.
