Description

Technical Field

[0001] The utility model relates to the technical field of hand wheels, in particular to a pre-selection ore-dropping hand wheel structure. Background Art

[0002] Most of the existing handwheel structures are disc-shaped. During use, the operator opens or closes the corresponding valve by turning the disc handwheel.

[0003] Usually, the corresponding valves are relatively tight due to the actual situation on site, and require a lot of force to turn. Therefore, how to turn the handwheel with less effort is a difficult problem that needs to be solved urgently. Utility Model Content

[0004] The utility model aims at the deficiencies in the prior art and provides a hand wheel structure for placing ore before selection.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A pre-selection ore-releasing handwheel structure comprises a handwheel body. A plurality of pairs of support rods are fixedly arranged on one side of the handwheel. The connecting lines of the pairs of support rods all pass through the center of the handwheel body and are located at the diameter position of the handwheel body. The paired support rods are connected with rotating rods, and the length of the rotating rods is greater than the length between the two support rods.

[0007] Furthermore, the rotating rod is detachably connected to the supporting rod.

[0008] Furthermore, a fixing screw is threadedly connected to the end of the support rod, a waist-shaped hole is opened on the end of the rotating rod, and the fixing screw passes through the waist-shaped hole and is placed in the waist-shaped hole to slide left and right.

[0009] Furthermore, the ends of the rotating rods are respectively provided with anti-slip sleeves.

[0010] Furthermore, a wear-resistant sleeve is provided on the support rod.

[0011] Furthermore, the anti-slip sleeve is detachably connected to the rotating rod.

[0012] Furthermore, the wear-resistant sleeve is detachably connected to the support rod.

[0013] Furthermore, rotating rings are provided at both ends of the rotating rod.

[0014] In summary, compared with the prior art, the above technical solution has the following beneficial effects:

[0015] (1) When the operator needs to turn the handwheel, the turning rod is installed on the handwheel body through the support rod, and the length of the turning rod is greater than the diameter of the handwheel body, so that the operator can better apply force to the handwheel body. When encountering greater resistance, the handwheel can be turned with less effort.

[0016] (2) The operator can choose to install or remove the rotating rod according to the actual situation. If a large force is required when the rod is first turned, the rotating rod can be installed. After the rotation, the resistance is small when the hand wheel is turned subsequently, so the rotating rod can be removed. The detachable type can be selected according to the actual working conditions.

[0017] (3) The waist-shaped hole enables the rotating rod to slide a certain distance along the diameter direction of the handwheel body. When the operator uses the rotating rod, the relative position of the rotating rod can be adjusted and offset to one side by a certain distance, so that the operator can better use the rotating rod.

[0018] (4) Both the anti-slip sleeve and the wear-resistant sleeve are made of rubber and have certain elasticity and anti-slip properties, making it easier for operators to hold and use them more comfortably. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] Reference Figure 1-Figure 2 The utility model embodiment discloses a pre-selection ore-release handwheel structure, comprising a handwheel body 1, which is generally arranged in a disc shape. When in use, the handwheel body 1 is rotated to control the opening and closing of the valve at the corresponding position. The pre-selection filter press ore-release place needs to be started and stopped by a manual cycle switch to complete the ore-release operation, so as to ensure that the ore-release buffer tank has sufficient liquid level.

[0024] A plurality of pairs of support rods 2 are fixedly provided on one side of the handwheel body 1, and are generally arranged in pairs. In the embodiment of the utility model, two support rods 2 passing through the center of the handwheel body 1 are a pair, and the connecting lines of the support rods 2 all pass through the center of the handwheel body 1 and are located at the diameter position of the handwheel body 1. The support rods 2 are arranged around the edge of the handwheel body 1 and are arranged in pairs in a central symmetric manner about the center of the handwheel body 1. When the operator uses it, he can hold the support rods 2 and rotate the handwheel body 1.

[0025] The support rod 2 is covered with a wear-resistant sleeve 4, which is made of rubber and has certain elasticity and anti-slip properties, so that the operator can hold and use it more comfortably. When the operator operates with bare hands, it is easy to cause damage to the hands due to the different opening and closing forces, and the wear-resistant sleeve 4 plays a better protective role.

[0026] The wear-resistant sleeve 4 is detachably connected to the support rod 2. When the wear-resistant sleeve 4 is severely worn after being used for a long time, it can be replaced.

[0027] The paired support rods 2 are connected with a rotating rod 5, and the length of the rotating rod 5 is greater than the length between the two support rods 2. When the operator needs to turn the hand wheel, the rotating rod 5 is arranged, and the rotating rod 5 is installed on the hand wheel body 1 through the support rods 2, and the length of the rotating rod 5 is greater than the diameter length of the hand wheel body 1, so that the operator can better apply force to the hand wheel body 1, and can turn the hand wheel with less effort when encountering greater resistance.

[0028] The rotating rod 5 is detachably connected to the supporting rod 2. The operator can choose to install or remove the rotating rod 5 according to the actual situation. When a large force is required at the beginning of the rotation, the rotating rod 5 can be installed. After the rotation, the resistance is small when the hand wheel is subsequently turned, and the rotating rod 5 can be removed. The detachable selection is made according to the actual working conditions.

[0029] The end of the support rod 2 is threadedly connected with a fixing screw 3, and a waist-shaped hole 6 is opened on the end of the rotating rod 5. The fixing screw 3 passes through the waist-shaped hole 6 and is placed in the waist-shaped hole 6 to slide left and right. The setting of the waist-shaped hole 6 enables the rotating rod 5 to slide a certain distance along the diameter direction of the handwheel body 1. When the operator uses the rotating rod 5, its relative position can be adjusted and offset to one side by a certain distance, so that the operator can better use the rotating rod 5.

[0030] The ends of the rotating rod 5 are respectively covered with anti-skid sleeves 7. The anti-skid sleeves 7 are made of rubber and have certain elasticity and anti-skid properties, so that the operator can hold and use it more comfortably. When the operator operates with bare hands, it is easy to cause damage to the hands due to the different opening and closing forces, and the anti-skid sleeves 7 play a better protective role.

[0031] The anti-skid cover 7 is detachably connected to the rotating rod 5. When the anti-skid cover 7 is worn out after long-time use, it can be replaced.

[0032] Rotating rings 8 are provided at both ends of the rotating rod 5 , which further facilitates the operator to hold and use the rotating rod 5 .

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
