Description

Technical Field

[0001] The utility model relates to the technical field of vehicle pressing beam structure transformation, in particular to a point-type vehicle pressing beam mechanism for a dumper. Background Art

[0002] During the tipping process, a car tipper requires a hold-down beam to hold the carriage down. Currently, domestic manufacturers primarily use two types of hold-down beams: the pendulum type and the point-type. The pendulum type is a more primitive type of hold-down structure, and the train tipper at Angang's raw material yard currently uses the pendulum type. Compared to the point-type, the pendulum type suffers from a significant drawback: the tendency to carry material over during tipping. Previously, migrant workers were tasked with clearing the bottom material from the carriages. Recently, to reduce labor costs, many of these workers have been laid off, severely restricting normal production.

[0003] Based on the current status of Angang's car tippers, the problem of material carrying over is quite serious, and the labor shortage is particularly severe, which has a great impact on normal production. It is necessary to take measures to technically transform the pressure beam of the car tippers to reduce the disadvantages of material carrying over and reduce the workload of cleaning the bottom material.

[0004] The existing point-type car pressing beam mechanism of a car tipping machine uses a car press to squeeze the car that needs to be unloaded. Direct car pressing will be unstable and prone to slipping. At the same time, a clamping hook is generally provided to clamp the unloading car. However, the general clamping hook cannot be adjusted in position and cannot be applied to different unloading cars. In addition, the mechanical adjustment operation will absorb a large amount of dust when exposed to the air for a long time. If it is not cleaned, it will affect the normal operation of the machine. For example, the Chinese utility model patent with the authorization announcement number CN207497712U discloses a mechanical buffer type car pressing beam of a car tipping machine, including a car press, a side beam fixing sleeve, a hydraulic cylinder, a spring unloading device, a car pressing beam base and a diagonal tie rod. The car press is connected to the hydraulic cylinder through the side beam fixing sleeve, and the hydraulic cylinder base is connected to the upper part of the spring unloading device. The entire car pressing beam is fixed to the car pressing beam base through the spring unloading device fixing bottom plate. The car pressing beam base is connected and fixed to the bottom beam of the car tipping machine and is assisted by the diagonal tie rod. A spring unloading device connects the car pressing beam to the car pressing beam base, reducing the impact of the wheel spring's elastic potential energy and the hydraulic cylinder's impact on the fixed point, solving the problem of cracking at the fixing point between the car pressing beam and the bottom beam of the dumper. However, this device uses a car pressing device to squeeze the car to be unloaded. Direct pressing of the car is unstable and prone to slipping. Therefore, we propose a point-type car pressing beam mechanism for the dumper to solve the above-mentioned problems. Utility Model Content
