Description

Technical Field

[0001] The utility model relates to the technical field of car frames, in particular to a freight elevator shaft structure. Background Art

[0002] With the rapid development of society, freight elevators are used more and more widely in various buildings, such as factories, warehouses, shopping malls, hotels, airports, stations and other places. Traditional freight elevator cars are mostly made of ordinary steel, which is heavy, low in strength, and easy to corrode. They are prone to deformation and breakage after long-term use, affecting the safety and service life of the freight elevator.

[0003] For example, a new type of traction freight elevator disclosed in a Chinese patent with patent application number CN202220148089.6 includes a freight elevator; a load-bearing device, and the load-bearing device includes a load-bearing plate, a ladder plate, a drive assembly and a positioning assembly. When unloading, this type of freight elevator drives the connecting seat to move through the cylinder, and drives the screw sleeve to move along the axial direction of the screw. The connecting seat is fixed to the loading plate, and the angle of the loading plate can be lifted so that the goods slide off the loading plate. The unloading efficiency is high, and there is no need for personnel to pull the goods, thus avoiding the problem of people being injured by pulling.

[0004] However, in the above structure, the car door needs to open to both sides, so enough space to accommodate the car door needs to be reserved on both sides of the elevator shaft, which will increase the width of the elevator shaft, resulting in excess space on both sides of the elevator shaft that cannot be used. Even if the counterweight is placed in the space on one side, at least the space on the other side will be wasted, which will not only increase the design difficulty but also increase the cost of the elevator.

[0005] Moreover, since the elevator plate is set at the bottom of the car, the weight of the car when loaded is concentrated on the car floor, which can easily cause deformation or breakage of the connection between the car floor and the car side wall. In addition, since there are no stabilizing structural components on the outer wall of the car, this type of freight elevator cannot load cargo that is too heavy, otherwise it will easily cause damage to the car.

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, but the utility model is not limited to the following embodiments.

[0025] like Figures 1 to 4As shown, the present embodiment discloses a freight elevator shaft structure, including an elevator shaft 1, a car 2, a counterweight 3 and an elevator door 4. At least 2 / 3 of the space on one side of the elevator shaft 1 is used to accommodate the car 2, and at least 1 / 3 of the space on the other side of the elevator shaft 1 is used to accommodate the counterweight 3. The elevator door 4 is installed at the position corresponding to the door of the car 2 and slides to the side close to the counterweight 3 to open. Preferably, in order to enable the elevator door 4 to be completely hidden behind the wall when opened, the elevator door 4 is provided with at least two layers. In the open door state, the elevator doors 4 are overlapped, and in the closed door state, the elevator doors 4 are arranged in sequence and unfolded. Furthermore, the elevator shaft 1 Main guide rails 5 for guiding the car 2 are provided on both sides of the car 2, and auxiliary guide rails 6 for guiding the counterweight 3 are provided on both sides of the counterweight 3 in the elevator shaft 1. A plurality of groups of C-shaped frames 7 are provided on the wall close to the counterweight 3 in the elevator shaft 1. The plurality of groups of C-shaped frames 7 are arranged in sequence along the depth direction of the elevator shaft 1 to form a lifting space 8 for the counterweight 3 to move up and down. The two groups of auxiliary guide rails 6 are symmetrically fixed on the inner side of the lifting space 8, and the two sides of the counterweight 3 are slidably matched with the auxiliary guide rails 6. Preferably, one of the main guide rails 5 is fixed on the outer side of the C-shaped frame 7, and the main guide rail 5 on the other side is fixed on the wall away from the counterweight 3.

[0026] In this embodiment, the car 2 is provided with a car frame 9 for improving structural strength and for cooperating with the main rails 5 on both sides to slide. The car frame 9 includes car frame columns 90 arranged on both sides of the car 2, upper support plates 91 connected to the upper ends of the car frame columns 90 on both sides, and lower support plates 92 connected to the lower ends of the car frame columns 90 on both sides. A plurality of groups of balancing rods 93 for fixing and supporting the bottom plate of the car 2 are arranged along the length direction on the lower support plate 92. The plurality of groups of balancing rods 93 are arranged in the front and rear directions of the car 2. At the same time, the front and rear ends of the plurality of groups of balancing rods 93 are provided with connecting rods 94. The connecting rods 94 connect the plurality of groups of balancing rods 93 to form a balancing frame as a whole. This can not only improve the stability of the car 2, but also improve the structural strength of the bottom plate of the car 2. Specifically, in the balancing frame, limiting mechanisms 95 for preventing the balancing frame from slipping are respectively provided between the two outermost balancing bars 93 and the car frame columns 90 on both sides. The limiting mechanisms 95 include fixing ears 950 arranged on both sides of the car frame columns 90 and limiting rods 951 connected between the fixing ears 950 and the balancing bars 93. The two limiting rods 951 and the balancing bars 93 form an isosceles triangle structure. When the balancing frame tends to slip, the limiting rods 951 located on both sides of the car frame columns 90 will pull each other to offset the sliding tendency, thereby achieving a limiting effect. In order to improve the limiting effect, the fixing ears 950 are arranged at a position close to the top of the car frame columns 90 so that the vertices of the isosceles triangle structure formed are acute angles.

[0027] In this embodiment, a car top wheel assembly 96 for connecting a steel wire rope is further provided on the top of the car frame 9, and the car top wheel assembly 96 includes a wheel axle 960 fixed on an upper support plate 91 and a rope pulley 961 rotatably mounted on the wheel axle 960. In order to facilitate the installation of the wheel axle 960 and the rope pulley 961, the upper support plate 91 is provided with two groups, and the two groups of upper support plates 91 are symmetrically arranged on both sides of the car frame column 90. A spacing L for accommodating the rope pulley 961 is formed between the two groups of support plates. The two ends of the wheel axle 960 are respectively fixed on the lower sides of the two groups of upper support plates 91. In this way, the car frame 9 can be pulled up by relying solely on the wheel axle 960, the structure is more stable, and the connecting parts are not easy to loosen.

[0028] In this embodiment, after the car 2 is fixed on the balance frame, the balance frame needs to be fixed on the lower support plate 92. In order to facilitate fixation, the cross-section of the lower support plate 92 is set to a horn-shaped structure. The middle part of the lower support plate 92 is a structural groove 920 for accommodating the car frame column 90. The two sides of the lower support plate 92 extend outward to form a fixed edge 921 for fixing the balance frame. Bolts are passed upward from the bottom of the fixed edge 921 through the fixed edge 921 and the balance frame and tightened to fix.

[0029] In this embodiment, a guide shoe 901 for cooperating with the main rail 5 is provided on the top of the car frame column 90, and a safety clamp 902 for emergency braking is provided on the bottom of the car frame column 90, so that the safety of the car 2 can be improved.
