Description

Blocking device for low space

Technical Field

The invention belongs to the technical field of conveying lines, and particularly relates to a blocking device for a low space.

Background

The stopping device used in the existing conveying line field (Chinese patent application No. 201922435305.6, name: pneumatic stopper used on conveyor) has the structure that a cylinder is additionally provided with two side guide rods, the working principle is that the cylinder extends out, but the stopping device has the following defects: the vertical direction occupies a large space and is difficult to bear large horizontal impact force, and even if the vertical direction can bear larger horizontal impact force, a plurality of devices are required to be added for realization; in addition, the service life of the steel plate is greatly shortened under the condition of bearing large impact force for a long time.

Disclosure of Invention

In order to overcome the disadvantages of the prior art, the invention aims to provide a blocking device for a low space, which changes the force output direction of the blocking device and greatly reduces the space occupation in the height direction; the device has simple structure and reduces the cost; can bear great horizontal force and impact force; the installation is simple swift, easy to maintain, and the commonality is strong.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a stop device for low space, is connected with guide block subassembly 3 including connecting push rod subassembly 2 on the bottom plate on push rod subassembly 2, is connected with on the guide block subassembly 3 and blocks subassembly 1.

Stop subassembly 1 glue and baffle 11 including the excelling in, excelling in glues and baffle 11 is connected in barrier plate 12 top, barrier plate 12 below is connected in swing arm 13 top, 13 front end below of swing arm and the cooperation of push rod subassembly 2, 13 rear end of swing arm end are connected on swing arm support 14, swing arm support 14 is connected on the bottom plate.

Push rod subassembly 2 include push rod 21, push rod 21 passes through push rod fixing base 22 to be fixed on the bottom plate, push rod 21 and the 23 middle parts of transmission shaft are connected, transmission shaft 23 is connected on

guide block subassembly

3, 23 both ends of transmission shaft are connected with follower bearing 24, follower bearing 24 and swing arm 13 below contact.

The guide block assembly 3 comprises a guide block 31, the guide block 31 is connected to the bottom plate, a guide bearing 32 is arranged on the guide block 31, and the guide bearing 32 is sleeved on the transmission shaft 23.

Compared with the prior art, the invention has the following technical effects:

(1) the invention installs the power horizontally, thus has saved the space of the direction of height, has changed the conducting direction of the push rod 21 force in combination with the way similar to the cam, thus make the push rod 21 not receive the horizontal force, thus play a role in protecting;

(2) the invention changes the output direction of the blocking device and greatly reduces the space occupation in the height direction;

(3) the device has simple structure and reduces the cost;

(4) the invention can bear great horizontal force and impact force;

(5) the installation is simple swift, easy to maintain, and the commonality is strong.

Detailed Description

The invention is described in detail below with reference to the figures and examples.

Referring to fig. 1, a blocking device for a low space includes a push rod assembly 2 connected to a bottom plate, a guide block assembly 3 connected to the push rod assembly 2, and a blocking assembly 1 connected to the guide block assembly 3.

Referring to fig. 2, the blocking assembly 1 comprises a high-strength rubber and baffle 11, a blocking plate 12, a swing arm 13 and a swing arm support 14, the high-strength rubber and baffle 11 is connected above the blocking plate 12, the lower part of the blocking plate 12 is connected above the swing arm 13, the lower part of the front end of the swing arm 13 is matched with the push rod assembly 2, the end head of the rear end of the swing arm 13 is connected on the swing arm support 14, and the swing arm support 14 is connected on the bottom plate.

Referring to fig. 3, the push rod assembly 2 includes a push rod 21, a push rod fixing seat 22, a transmission shaft 23 and a follower bearing 24, the push rod 21 is fixed on the bottom plate through the push rod fixing seat 22, the middle parts of the push rod 21 and the transmission shaft 23 are connected through a connecting piece, the transmission shaft 23 is connected on the guide block assembly 3, the two ends of the transmission shaft 23 are connected with the follower bearing 24, and the follower bearing 24 is in contact with the lower part of the swing arm 13.

Referring to fig. 4, the guide block assembly 3 includes a guide block 31, the guide block 31 is connected to the base plate, a guide bearing 32 is disposed on the guide block 31, and the guide bearing 32 is sleeved on the transmission shaft 23.

The working principle of the invention is as follows: referring to fig. 5, when the push rod 21 extends out, the guide bearing 32 moves forwards horizontally along the guide block 31, the transmission shaft 23 drives the follow-up bearing 24 to move forwards, meanwhile, the swing arm 13 rotates around the swing arm support 14 under the effect of the follow-up bearing 24 to drive the high-strength rubber and the baffle 11 to move upwards, the blocking effect is achieved, the horizontal stress of the whole blocking device is borne by the swing arm support 14 at the moment, and the push rod 21 does not bear the blocking force, so that the good protection effect can be achieved.
