Description

Technical Field

[0001] This utility model relates to a cement specimen curing device. Background Technology

[0002] Before conducting various strength tests on cement specimens, the specimens need to be cured in a curing chamber. The main control factors involve the curing temperature, humidity, and time. During the curing period, temperature and humidity data need to be collected regularly to ensure that the curing meets the relevant specifications and standards.

[0003] Cement specimens are typically processed in batches. To reduce the cost of curing chambers, existing curing chambers are becoming increasingly larger, with a single temperature and humidity control system capable of meeting the testing needs of large batches of cement specimens. However, in reality, not every batch of specimens can completely fill the curing chamber. To ensure constant temperature and humidity during curing, the curing of the next batch of specimens can only begin after the first batch has been cured and emptied. This results in a significant waste of curing chamber space and is time-consuming. Another approach is to introduce the second, and even third or fourth batches of specimens before the first batch has finished curing. While this solves the problem of wasted curing chamber space and time, it requires frequent opening and closing of the curing chamber door, and the time spent filling the chamber with cement specimens is relatively long, leading to large fluctuations in temperature and humidity within the curing chamber. The curing temperature and humidity of the previous batches of cement specimens may not meet the requirements of the specifications. Summary of the Invention

[0004] The purpose of this invention is to provide a cement specimen curing box that can introduce cement specimens to be cured in batches, and minimize the impact of the introduction of subsequent batches of cement specimens on the curing environment (temperature, humidity) of the previous batches of cement specimens.

[0005] This utility model is specifically implemented as follows:

[0006] This cement specimen curing chamber includes at least two adjacent curing chambers, a controller, and a temperature and humidity control kit. The at least two adjacent curing chambers are arranged horizontally side by side (e.g., 2, 3, or 4), vertically side by side (e.g., 2, 3, or 4), or in an array (e.g., 4, 6, or 8).

[0007] Understandably, each curing chamber can be equipped with a temperature-humidity control kit. This kit may include both temperature and humidity control components, as some cases require only temperature adjustment, others only humidity adjustment, and still others require simultaneous adjustment of both. The temperature control kit includes a heater, cooler, and / or temperature sensor, while the humidity control kit includes a humidifier, dehumidifier, and / or humidity sensor.

[0008] The temperature-humidity control kit is arranged inside the curing chamber and electrically connected to the controller. The controller controls the operation of the temperature-humidity control kit according to the set requirements, and controls the operation of the heater, cooler and / or humidifier and dehumidifier based on the feedback from the temperature sensor and / or humidity sensor of the temperature-humidity control kit, until the temperature and / or humidity of the curing chamber meet the test requirements.

[0009] Adjacent curing chambers are separated by openable and closable partitions, which have a passable state and a closed state. In the passable state, adjacent curing chambers are connected by the partition; in the closed state, adjacent curing chambers are separated by the partition. The system also includes a linkage mechanism between the curing chamber doors and the openable and closable partitions. Each curing chamber includes an independent door. When both doors of two adjacent curing chambers are closed, the linkage mechanism causes the openable and closable partition to enter the passable state; when one door of one of the two adjacent curing chambers is open and the other door is closed, the linkage mechanism causes the openable and closable partition to enter the closed state. The advantage of this arrangement is that, for example, in a curing chamber with adjacent first and second curing chambers, the first batch of cement specimens is cured in the first curing chamber. During the curing period, the first and second curing chambers are connected and are in the set temperature and humidity environment. When it is necessary to introduce the second batch of cement specimens, the curing chamber door of the second curing chamber is opened, and the openable and closable partition is in a closed circuit state, so the test environment in the first curing chamber is basically unaffected.

[0010] The structure of an openable and closable partition can take many forms, such as a partition with a valve. One form of this openable and closable partition includes a first partition and a second partition stacked together, with a plurality of first partition holes and second partition holes respectively provided on the first partition and the second partition. When the first partition and the second partition are aligned, their respective holes are also aligned, i.e., in a passable state. When the first partition and the second partition are staggered, their respective holes are blocked from each other, i.e., in a closed state.

[0011] The linkage mechanism can be either mechanical or electrical.

[0012] A mechanical linkage mechanism may include a push-pull plate, a first lever, a door hinge gear, and a reduction gear. Each of the first and second partitions has a push-pull plate at one end, with a first protrusion and a second protrusion on the push-pull plate. The curing chamber door is hinged to the cement specimen curing box shell via a pin at one end of the door. The door hinge gear is fixed to the pin and meshes with the reduction gear. One end of the first lever is fixed to the reduction gear, and the other end is positioned between the first and second protrusions. Rotation of the curing chamber door causes the first lever to swing, thereby causing the corresponding first partition (or second partition) to move longitudinally, thus switching the openable / closed partition between a passable and closed state.

[0013] It is understandable that the reciprocating swing amplitude of the first lever is achieved through the speed-changing structure of meshing gears, thereby realizing the switching between alignment and staggering of the first and second partitions. Of course, the essence of mechanical transmission is not limited to the above method. For example, gear transmission does not necessarily involve two gears, nor does it necessarily require the swinging of the first lever for operation. It can also be converted into linear motion through the cooperation of gears and racks to drive the longitudinal movement of the first partition (or the second partition).

[0014] An electrical linkage mechanism includes a push-pull plate, a second lever, a sensor switch, and a telescopic rod. Each of the first and second partitions has a push-pull plate at one end, and the outer end of the push-pull plate is fixed to the electric telescopic rod. The sensor switch and the telescopic rod are electrically connected to a controller. The curing chamber door is hinged to the housing of a cement specimen curing box via a pin at one end of the door. One end of the second lever is fixed to the pin, and the other end of the second lever abuts against the sensor switch when the curing chamber door is closed. Rotation of the curing chamber door causes the second lever to swing. The sensor switch detects the approach and departure of the second lever. Based on the sensor switch's detection, the controller controls the extension and retraction of the telescopic rod, causing the corresponding first (or second) partition of the curing chamber door to move longitudinally, thereby switching the openable / closed partition between a closed and open state.

[0015] Similarly, electrical linkages do not necessarily use linear telescopic rods; they can also draw inspiration from the swinging structure of mechanical linkages.

[0016] In addition, the maintenance chamber door also includes a handle and / or an observation window to facilitate the operation of the maintenance chamber door and external observation.

[0017] The cement specimen curing box proposed in this utility model adopts multiple curing chambers that can be arranged in a partitioned manner, and cement specimens to be cured can be introduced in batches. During the introduction of subsequent batches of cement specimens, the curing chambers of the previous batch can be kept in a closed space, thereby minimizing the impact on the curing environment (temperature and humidity) of the previous batch of cement specimens.

[0027] Example 1

[0028] See Figure 1-5The cement specimen curing box 100 of this utility model includes two adjacent vertically arranged first curing chambers 11 and second curing chambers 12, a controller 13, and a temperature-humidity regulating kit 14. Each of the first and second curing chambers 11 and 12 includes an independent curing chamber door 16. Multiple layers and / or multiple rows of frame structures or drawer structures can be arranged inside the first and second curing chambers 11 and 12 as needed for placing cement specimens (not shown in the figure). The temperature-humidity regulating kit 14 is arranged in both the first and second curing chambers 11 and 12, and the temperature-humidity regulating kit 14 is electrically connected to the controller 13. The first and second curing chambers 11 and 12 are separated by an openable and closable partition 15, which includes stacked first partitions 151 and second partitions 152. Multiple first partition holes 1511 and second partition holes 1521 are respectively provided on the first and second partitions 151 and 152. When the first partitions 151 and 152 are aligned (see...),... Figure 4 Their respective holes 1511 and 1521 are also in an aligned state, that is, in a passable state, and the first curing chamber 11 and the second curing chamber 12 are connected by an openable and closable partition 15; when the first partition 151 and the second partition 152 are misaligned (see Figure 5 Their respective holes 1511 and 1521 are blocked from each other, i.e., they are in an open circuit state. The first curing chamber 11 and the second curing chamber 12 are separated by an openable and closable partition 15.

[0029] The cement specimen curing box 100 also includes two sets of linkage mechanisms, which act on the first partition 151 and the second partition 152 respectively. Figure 4-6 Only one set of the linkage mechanism acting on the first partition 151 is shown in the figure. The linkage mechanism includes a push-pull plate 17, a first lever 18, a door shaft gear 19, and a reduction gear 20. The first partition 151 and the second partition 152 are each provided with a push-pull plate 17 at one end. The push-pull plate 17 is provided with a first protrusion 171 and a second protrusion 172. The curing chamber door 16 is hinged to the housing of the cement specimen curing box 100 by a pin 161 provided at one end of the curing chamber door 16. The door shaft gear 19 is fixed to the pin 161 and meshes with the reduction gear 20. One end of the first lever 18 is fixed to the reduction gear 20, and the other end of the first lever 18 is placed between the first protrusion 171 and the second protrusion 172.

[0030] In actual use, the first batch of cement specimens is placed in the second curing chamber 12, the curing chamber doors 16 of the first curing chamber 11 and the second curing chamber 12 are closed, the humidity and / or temperature of the curing chamber are set by the controller 13, and the temperature-humidity regulating kit 14 is activated to start the curing of the first batch of cement specimens. At this time, the first partition 151 and the second partition 152 are aligned, and the first partition hole 1511 and the second partition hole 1521 are also aligned, that is, in a passable state. The first curing chamber 11 and the second curing chamber 12 are both in a constant temperature and humidity environment. When the curing of the second batch of cement specimens is required during the curing of the first batch of cement specimens, the curing chamber door 16 of the second curing chamber 12 remains closed, and the curing chamber door 16 of the first curing chamber 11 is opened. During the opening process, the curing chamber door 16 drives and rotates around the pin 161, thereby driving the door shaft gear 19 and the reduction gear 20 to rotate, so that the first lever 18 swings outward and abuts against the second protrusion 172, thereby driving the first partition 151 to move longitudinally outward, so that the first partition 151 and the second partition 152 are misaligned. The holes 1511 and 1521 of the first partition are blocked by the non-hole parts of the second partition 152 and the first partition 151, respectively. Then the second batch of cement specimens is placed into the first curing chamber 11. The first maintenance chamber 11 is closed by the maintenance chamber door 16. In contrast to opening the first maintenance chamber 11, the first lever 18 swings inward and abuts against the first protrusion 171, thereby causing the first partition 151 to move longitudinally inward, so that the first partition 151 and the second partition 152 are aligned again.

[0031] Example 2

[0032] See Figure 1-3 6. Unlike embodiment 1, an electrical linkage mechanism is used. The linkage mechanism includes a push-pull plate 17, a second lever 21, an induction switch 22, and a telescopic rod 23. The first partition 151 and the second partition 152 are each provided with a push-pull plate 17 at one end. The outer end of the push-pull plate 17 is fixed to the electric telescopic rod 23. The induction switch 22 and the telescopic rod 23 are electrically connected to the controller 13. The curing chamber door 16 is hinged to the housing of the cement specimen curing box 100 by a pin 161 set at one end of the curing chamber door 16. One end of the second lever 21 is fixed to the pin 161. The other end of the second lever 21 abuts against the induction switch 22 when the curing chamber door 16 is closed.

[0033] First, place the first batch of cement specimens in the second curing chamber 12, close the curing chamber doors 16 of the first curing chamber 11 and the second curing chamber 12, set the humidity and / or temperature of the curing chamber through the controller 13, and start the curing of the first batch of cement specimens by activating the temperature-humidity regulating kit 14. At this time, the first partition 151 and the second partition 152 are aligned, and the first partition hole 1511 and the second partition hole 1521 are also aligned, that is, in a passable state. The first curing chamber 11 and the second curing chamber 12 are both in a constant temperature and humidity environment. When the curing of the second batch of cement specimens is required during the curing of the first batch of cement specimens, the curing chamber door 16 of the second curing chamber 12 remains closed, and the curing chamber door 16 of the first curing chamber 11 is opened. During the opening process, the curing chamber door 16 drives and rotates around the pin 161, thereby driving the second lever 21 away from the induction switch 22. The signal of moving away from the induction switch 22 is collected by the controller 13 and controls the telescopic rod 17 to retract, thereby driving the first partition 151 to move longitudinally outward, so that the first partition 151 and the second partition 152 are staggered. The holes 1511 and 1521 of the first partition are blocked by the non-hole parts of the second partition 152 and the first partition 151, respectively, and the second batch of cement specimens are placed into the first curing chamber 11. Then, the maintenance chamber door 16 of the first maintenance chamber 11 is closed. In contrast to opening the maintenance chamber door 16 of the first maintenance chamber 11, the second lever 21 approaches and abuts against the induction switch 22. The signal of approaching and abutting against the induction switch 22 is collected by the controller 13 and controls the extension rod 17 to extend, thereby driving the first partition 151 to move longitudinally inward so that the first partition 151 and the second partition 152 are aligned again.

[0034] Example 3

[0035] See Figure 7 The only difference from Embodiments 1 and 2 is that it includes four curing chambers arranged in an array, wherein the walls shared by adjacent curing chambers arranged in the horizontal direction can also be equipped with openable and closable partitions 15. Of course, the walls shared by adjacent curing chambers arranged in the horizontal direction are solid walls that are always in an open circuit state, so that the two vertical rows of curing chambers have the structure of Embodiments 1 and / or Embodiment 2 respectively, and the two vertical rows of curing chambers are independently controlled by the controller 13.

[0036] Example 4

[0037] The difference from Examples 1-3 is that the multiple curing chambers have different volumes. For each batch of cement specimens, the empty curing chambers that maximize the filling rate are used preferentially, thereby improving the utilization rate of the curing chambers.

[0038] Additionally, a handle 162 and / or an observation window 163 can be provided on the curing chamber door 16 to facilitate the operation of the curing chamber door and external observation.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
