Description

Technical Field

[0001] The utility model relates to an elevator guide rail assembly, in particular to a guide rail pressing structure. Background Art

[0002] With the rapid development of the construction industry, high-rise buildings continue to emerge. Elevators are an important part of high-rise buildings, which facilitate the up and down movement of people or goods in high-rise buildings. Elevators mainly include straight elevators and inclined elevators. Straight elevators generally include a machine room part, a hoistway and a pit part, a floor station part and a car part. The car part is slidably assembled on the elevator guide rails and slides up and down driven by the traction machine. The elevator guide rails determine the safety and parallelism of the car's operation. The elevator guide rails are installed on the guide rail brackets. The two are assembled by pressing the guide plate. The shape and structure of the pressure guide plate are closely related to the connection stability of the elevator guide rails.

[0003] At present, when installing the pressure guide plate of the elevator guide rail, the pressure guide plate relies on friction to prevent the guide rail from moving laterally. However, during the long-term use of the elevator guide rail, the effect of the pressure guide plate to prevent the elevator guide rail from moving laterally through friction will gradually decrease;

[0004] In addition, during use, as the elevator moves up and down, it will generate certain vibrations. When the elevator vibrates, the vibration force will act on the elevator guide rails. When the elevator guide rails are subjected to the vibration force, they may move laterally. The lateral stability and reliability of the elevator guide rails are poor. Therefore, a guide rail clamping structure is proposed. Utility Model Content

[0005] The utility model aims to solve the above problems and proposes a guide rail pressing structure.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a clamping structure for a guide rail, comprising a fixed frame, a guide rail installed on the fixed frame, and a pressure guide plate for clamping the guide rail installed on the fixed frame; the characteristic is that it also includes a limiting structure arranged on the guide rail and the pressure guide plate, which limits the position of the pressure guide plate and the guide rail and also limits the position of the guide rail after clamping; the limiting structure includes a positioning groove arranged on the guide rail and a positioning protrusion arranged on the pressure guide plate and adapted to the positioning groove.

[0007] Further preferably, the positioning protrusion is formed by stamping.

[0008] Further preferably, the guide rail is also provided with an empty slot for inserting the pressure guide plate, one end of the pressure guide plate passes through the empty slot and is connected to the fixing frame, and the positioning protrusions are arranged on the pressure guide plate and are located in the positioning slots on both sides of the guide rail.

[0009] Further preferably, flanges are provided on both sides of the pressure guide plate to enhance the strength of the pressure guide plate.

[0010] Further preferably, it also includes an arch portion arranged on the pressure guide plate for improving the strength and anti-deformation of the pressure guide plate.

[0011] The beneficial effects of the utility model are as follows: by setting the limiting structure, the connection and pressing position of the pressing guide plate and the guide rail is limited, so as to avoid the lateral movement of the guide rail caused by vibration during use, thereby affecting the stability and reliability of the guide rail;

[0012] By setting an empty slot on the guide rail, one end of an integrated pressure guide plate is passed through the empty slot to press the two sides of the guide rail. One pressure guide plate can press the two sides of the guide rail, thereby enhancing the pressing effect and increasing the connection stability between the pressure guide plate and the guide rail, and the installation is convenient and quick.

[0013] By setting flanges on both sides of the pressure guide plate and an arch on the guide plate, the overall strength of the pressure guide plate is enhanced and the pressure guide plate's anti-deformation ability is enhanced to avoid deformation of the pressure guide plate due to vibration during use, thereby affecting the installation stability of the guide rail.

[0017] Next, we will further explain the clamping structure of a guide rail described in the present invention with reference to the accompanying drawings.

[0018] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0019] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation" and the like shall be used in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium; it may be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] See also Figure 1-2 As shown in the figure, a guide rail pressing structure comprises a fixing frame 1, a guide rail 2 mounted on the fixing frame 1, and a pressing guide plate 3 for pressing the guide rail 2 mounted on the fixing frame 1; the structure is characterized in that it also comprises a limiting structure arranged on the guide rail 2 and the pressing guide plate 3, which limits the position of the pressing guide plate 3 and the guide rail 2 and also limits the position of the guide rail 2 after pressing; the limiting structure comprises a positioning groove 4 arranged on the guide rail 2 and a positioning protrusion 5 arranged on the pressing guide plate 3 and adapted to the positioning groove 4;

[0021] By setting the limiting structure, the connection and pressing position between the pressing guide plate 3 and the guide rail 2 is limited, so as to avoid lateral movement of the guide rail 2 due to vibration during use, thereby preventing the stability and reliability of the guide rail 2 from being affected.

[0022] In one embodiment, the positioning protrusion 5 is formed by stamping, and the positioning protrusion 5 contacts and presses the guide rail 2 while clamping the guide rail 2 in the positioning groove 4, thereby limiting the connection contact position between the pressure guide plate 3 and the guide rail 2.
