DETAILED DESCRIPTION

[0032] The technical solution of the present application is further described below in conjunction with specific embodiments, but the present application is not limited to these embodiments.

[0033] like Figures 1 to 7 As shown, this embodiment provides a safety guardrail for a negative pressure vacuum casting process. The safety guardrail is arranged at the opening of a casting well 11. A mounting groove 12 connected to the casting well 11 is provided on the ground. The safety guardrail includes:

[0034] A bottom plate 13 is provided at the bottom of the mounting groove 12;

[0035] A support plate 14 is fixed to the base plate 13 , and a first guide rail 15 is provided on an upper end surface of the support plate 14 ;

[0036] a movable plate 16 , the movable plate 16 being arranged on the first guide rail 15 via a first slider 17 ;

[0037] A railing assembly 18, wherein the railing assembly 18 is fixed to an end of the movable plate 16 facing the casting well 11;

[0038] The driving mechanism 19 is used to control the reciprocating motion of the movable plate 16 .

[0039] The technical effect of this solution is that, by providing a movable guardrail mechanism, an operator stands on a movable plate 16 and adjusts the operator's position via a drive mechanism 19. Each time a row of aluminum bars is moved, the drive mechanism 19 drives the movable plate 16 a certain distance toward the casting pit 11, allowing the operator to effectively adjust the position of the aluminum bars. Furthermore, a guardrail assembly 18 is provided on the movable plate 16 to protect the operator, preventing the aluminum bars from being hoisted into the air or from being hit by the loading end of the hoisting equipment.

[0040] As an implementation of this embodiment, a support portion 20 is fixed to the lower end of the movable plate 16 , and a roller 21 is installed at the lower end of the support portion 20 . The roller 21 is in pressure contact with the bottom plate 13 .

[0041] The technical effect of this solution is that it is used to effectively support the movable plate 16, improve the structural strength of the movable plate 16 by providing the support portion 20, and reduce the friction resistance at the bottom of the support portion 20 by providing the roller 21.

[0042] The driving mechanism 19 in this solution can be a cylinder or other forms. For example, the driving mechanism 19 includes:

[0043] A rack 22, the rack 22 being mounted on the lower surface of the movable plate 16 via a connecting seat 23;

[0044] A driving member 24, the driving member 24 is mounted on the base plate 13 via a support 31, and the driving member 24 has a rotatable output shaft;

[0045] The gear 25 is mounted on the output shaft of the driving member 24 , and the gear 25 is meshed with the rack 22 .

[0046] This solution uses a gear 25 rack 22 in the form of a form, which has the advantages of high precision and small installation space. Compared with the structure of a cylinder, due to the composition of the cylinder body and piston rod, it is inevitable that the flow will exceed the installation space of the cylinder body, which requires a larger installation space. This solution uses a gear 25 rack 22 in the form of a form, which significantly reduces the installation space of the drive mechanism 19.

[0047] The driving member 24 includes a motor and a reducer, and the motor is equipped with a gear 25 via the reducer. The motor is a servo motor. Figure 6 and Figure 7 The motor and reducer are not reflected. Figure 2The motor and reducer are shown in the figure. Since the motor and reducer are conventional equipment, their structures and numbers are not further explained.

[0048] As an implementation of this embodiment, the connecting seat 23 has a receiving groove 26 with an opening facing downward, and the rack 22 is fixed in the receiving groove 26 .

[0049] The technical effect of this solution is that the rack 22 is shielded and protected by providing the receiving groove 26 on the connecting seat 23 , thereby preventing contamination particles from falling on the rack 22 .

[0050] As an implementation of this embodiment, the connecting seat 23 includes:

[0051] a horizontal plate 27 , the horizontal plate 27 being fixed to the lower surface of the movable plate 16 , and the rack 22 being fixed to the lower surface of the horizontal plate 27 ;

[0052] The vertical plate 28 is fixed to the lower end surface of the horizontal plate 27 , and two vertical plates 28 are provided at both ends of the horizontal plate 27 in the width direction.

[0053] Furthermore, a second guide rail 29 is provided on the lower end surface of the vertical plate 28 ; a second slider 30 is fixed to the upper end surface of the support 31 , and the second slider 30 is slidably connected to the second guide rail 29 .

[0054] The technical effect of this solution is that it is used to enable smooth sliding between the connecting seat 23 and the support 31.

[0055] As an implementation method of this embodiment, the railing assembly 18 includes a main guardrail 32 and an extension guardrail 33. The main guardrail 32 is fixed on the movable plate 16, and the extension guardrail 33 can be slidably inserted into the installation port of the main guardrail 32, and the main guardrail 32 is provided with a screw 34 for tightening the extension guardrail 33.

[0056] The extended guardrail 33 can be stretched in the horizontal direction to increase the protection area and improve the safety of the operation.

[0057] In addition, a safety guardrail in this solution is provided on one side of the casting well 11, and fixed guardrails are used on the other three sides of the casting well 11 to prevent people from entering at will.

[0058] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
