Description

Shaft sleeve for quickly adjusting spiral jack support

Technical Field

The invention relates to a mechanical structure of a shaft sleeve, in particular to a shaft sleeve for quickly adjusting a screw type jack support.

Background

Screw jacks are a common mechanical structure that is often used to lift heavy objects. Some supports and machines requiring staged adjustment also often use screw jack structures. For example, in a scissor jack multipoint drive solar single-axis tracking support with the authorization publication number of CN104065332B, the jacks on each photovoltaic support are rotated through the transmission shafts, so as to achieve the purpose of adjusting the angles of the aligned photovoltaic supports.

If the purpose of accurately adjusting the angles of a large number of photovoltaic supports is to be achieved, angle sensors can be mounted on each photovoltaic support, and a motor is mounted on each group of photovoltaic supports with the angle to be adjusted. But the cost is too high, and because the installation environment of photovoltaic support bears sunshine and rain, equipment such as motor, sensor of installing in the field for a long time is very easily damaged.

If can design a portable adjustment tool, can adapt to the structure of photovoltaic support, through the handheld angle modulation mechanical tool that just can dock the photovoltaic support of staff, just can show reduce cost.

The requirement on the mechanical structure when the jack is butted with the jack is high, and the jack needs to be capable of being butted with the screw rod of the jack quickly and stably and separating quickly and stably.

Disclosure of Invention

The invention aims to provide a shaft sleeve for quickly butting a jack bracket, which can be quickly and stably butted with a jack and can be quickly and stably separated. In order to solve the technical problem, the adopted technical scheme is as follows:

the utility model provides a shaft sleeve for quick adjustment screw jack support which characterized in that: two sides of the end part of the shaft sleeve are provided with herringbone spiral grooves which are symmetrical with the axis.

As a further improvement, the other side of the end part of the shaft sleeve is connected with a rotating shaft of the motor.

As a further improvement, the device also comprises guide rods fixed on two sides of the shaft sleeve, wherein the guide rods on the two sides are parallel to each other, and positioning grooves are formed in the guide rods.

The invention has the beneficial effects that: 1. the herringbone spiral groove structure with the symmetrical axis can be quickly and stably butted with a screw rod of the jack and can be quickly and stably separated; 2. the guide rod can improve the stability of the jack in butt joint; 3. easy processing and low cost.

Detailed Description

The following provides a more detailed description of the embodiments and the operation of the present invention with reference to the accompanying drawings.

As shown in FIG. 1, the herringbone helical groove 11 is an exploded view of the connection relationship. The invention can be quickly and stably butted with the screw rod 22 of the jack 2 and can be quickly and stably separated. In order to facilitate the driving of the screw rod 22, it is common in the prior art to insert a rotating shaft pin 23 perpendicular to the screw rod 22 at the end of the screw rod 22.

In order to drive the screw rod 22 with its rotating axle pin 23 in rotation, it is common in the prior art to drive the sleeve 1 with a groove at the end, which is generally a straight groove matching the shape and size of the pin. The groove is improved to be a herringbone spiral groove 11 which is symmetrical with the axis at two sides of the end part of the shaft sleeve 1. When the pin joint is used, the pin joint is connected into the herringbone spiral grooves 11 on two sides, and gaps of the herringbone spiral grooves 11 are selected according to the rotating direction. The rotation direction is more stable than the straight line shape since the rotation direction is matched with the notch direction of the herringbone spiral groove 11 necessarily from the moment the rotating shaft pin 23 enters the notch to the moment the rotation is performed. When the shaft sleeve 1 is withdrawn, the pin enters the herringbone notch obliquely, so that the shaft sleeve 1 and the pin can be separated by turning a certain angle without directly pulling in the linear direction during separation, and the pin can be separated by using smaller force than the linear groove.

A motor is used in conjunction with the hub 1 to provide power to drive the screw 22 in rotation.

Referring to fig. 2, which is a connection relationship diagram of the present invention and the jack 2, the guide rods 12 are fixed to both sides of the shaft sleeve 1, the guide rods 12 are parallel to each other, and the guide rods 12 are provided with positioning grooves 121. The size of the positioning groove 121 needs to be set to match the size of the knuckle bolt 21. When in use, the joint bolts 21 at two sides of the jack 2 are positioned in the positioning grooves 121 in the guide rods 12 at two sides of the shaft sleeve 1.
